At present, the effect of the range hood cannot be evaluated and compared in the prior art, and a complete audio injection evaluation method and a transverse comparison method are not available, so that the range hood designed based on the audio injection method is not available in the market, and the sound of the range hood cannot be adjusted according to the audio injection effect. Based on the control method and device for the range hood and the range hood provided by the embodiment of the application.
The method mainly solves the evaluation problem of the audio injection effect of the range hood and the transverse comparison problem of the audio injection effect and other noise reduction measures, combines the subjective evaluation experiment of the annoyance degree, and provides the annoyance sense inhibition quantitative evaluation method based on the audio injection to obtain the relation between noise annoyance degree reduction and equivalent sound pressure level reduction, and quantitatively analyzes the inhibition effect on the noise annoyance degree when different regulation sounds are used in the audio injection of the range hood.
For the sake of understanding the present embodiment, first, a control method of a range hood disclosed in the present embodiment is described in detail.
Embodiment one:
the embodiment of the application provides a control method of a range hood, which is applied to a controller of the range hood, and is shown in a flow chart of the control method of the range hood in FIG. 1, and the control method of the range hood comprises the following steps:
step S102, a first relation curve of the sound annoyance degree variation and the sound pressure level variation is obtained.
The noise annoyance (Annoyance of Noise) refers to the annoying response caused by noise. The annoyance is closely related to the nature and characteristics of noise. In general, the annoyance of strong noise is greater than that of weak noise, the annoyance of high-frequency noise is greater than that of low-frequency noise of the same loudness, the annoyance of intermittent noise and impulse noise is greater than that of continuous steady-state noise, the annoyance of noise emitted by the machine is greater than that of natural noise of the same loudness, the annoyance of noise emitted at night is greater than that of noise occurring in daytime, the annoyance of noise with frequent change of sounding direction is greater than that of noise from a certain direction, and the annoyance of novel or unique noise is greater than that of familiar noise.
In this embodiment, the annoyance level may be quantified, and in general, the same sound annoyance level may be scored by a plurality of people, and a specific value of the sound annoyance level may be obtained according to the score. In this embodiment, the annoyance degrees are distinguished according to the sound pressure levels, that is, the user can score a plurality of sounds with different sound pressure levels, and then obtain a specific numerical value of the annoyance degrees of the sounds with the sound pressure levels according to the scores, that is, the annoyance degree evaluation experiment.
The specific values of the annoyance corresponding to the sounds with different sound pressure levels can be determined in the annoyance evaluation experiment, and accordingly, a first relation curve of the change amount of the annoyance of the sounds and the change amount of the sound pressure level can be drawn.
Step S104, obtaining the regulation sound of the range hood, and determining the annoyance change amount corresponding to the regulation sound; the regulation sound characterizes sound added into noise of the range hood.
In this embodiment, to apply the audio injection method to a range hood, the audio injection method is a noise control method that changes the hearing feeling of one sound (the target sound, generally the noise of the range hood itself) by adding another sound (the adjusting sound), so that the overall quality (such as comfort, pleasure, etc.) of the sound is improved. The sound after the regulated sound and the target sound are mixed is called as superposition sound.
The change of the annoyance degree corresponding to the regulating sound can be understood as the change of the annoyance degree before the regulating sound is added and the annoyance degree after the regulating sound is added, namely the change of the annoyance degree of the target sound and the annoyance degree of the superimposed sound after the regulating sound and the target sound are mixed.
And S106, determining the sound pressure level variation corresponding to the regulating sound based on the vexation degree variation corresponding to the regulating sound and the first sound relation curve.
The sound pressure level variable quantity corresponding to the annoyance degree variable quantity corresponding to the regulating sound can be determined by substituting the annoyance degree variable quantity corresponding to the regulating sound into the first sound relation curve. In this embodiment, the sound pressure level variation corresponding to the regulated sound can be used as a reference for evaluating the audio injection effect, the perceived effect after audio injection is quantitatively described, and the audio injection effect can be directly expressed by using equivalent decibel values. In addition, the embodiment can transversely compare the audio injection effect with the rest of noise reduction measures through the mode.
Step S108, adjusting the adjusting sound of the range hood based on the sound pressure level variation corresponding to the adjusting sound.
The adjusting sound of the range hood can be adjusted based on the sound pressure level variation, so that the superposition sound of the adjusted range hood has a more comfortable effect, and the use feeling of a user is improved. Specifically, if the sound pressure level variation corresponding to the regulation sound is too low, the regulation sound of the range hood can be improved; if the sound pressure level variation corresponding to the regulation sound is too high, the regulation sound of the range hood can be reduced.
According to the control method of the range hood, provided by the embodiment of the application, the sound pressure level variation corresponding to the regulating sound can be determined according to the first relation curve of the sound annoyance variation and the sound pressure level variation and the annoyance variation corresponding to the regulating sound, the effect of audio injection of the range hood is evaluated through the sound pressure level variation corresponding to the regulating sound, and the regulating sound of the range hood is regulated according to the sound pressure level variation corresponding to the regulating sound, so that a user obtains better use feeling of the range hood.
Embodiment two:
the present embodiment provides another control method of a range hood, which is implemented on the basis of the above embodiment, as shown in a flowchart of another control method of a range hood shown in fig. 2, where the control method of a range hood in this embodiment includes the following steps:
step S202, a second relation curve of the preset sound annoyance degree and the sound pressure level is obtained.
In this embodiment, a second relationship curve of the preset sound annoyance level and the sound pressure level may be obtained through a pure-tone annoyance level evaluation experiment. The second relation curve of the sound annoyance level and the sound pressure level can be drawn based on a preset reference sound sample in the pure sound annoyance level evaluation experiment; specifically, the reference sound sample is preferably a pure tone of frequency 1kHz at a sound pressure level of 70 dB.
In the pure tone annoyance degree evaluation experiment, 1kHz and 70dB pure tone are used as reference sound samples, and the pure tone annoyance degree experiment can be carried out by the following steps: acquiring a reference sound sample and a plurality of samples to be evaluated; wherein, the sound pressure levels of a plurality of samples to be evaluated are different; playing a reference sound sample and a plurality of samples to be evaluated to a plurality of testees; receiving the vexation degree scores of a plurality of samples to be evaluated sent by a plurality of tested persons; and drawing a second relation curve of sound annoyance and sound pressure level based on the annoyance scores of the samples to be evaluated and the sound pressure levels of the samples to be evaluated. The annoyance evaluation experiment is described:
a) Evaluation index: according to the noise characteristics of the range hood, the annoyance degree is established as an index for representing the sound quality.
b) Evaluation scale: taking 1-9 as a vexation degree 9-level evaluation scale;
c) Test (may also be referred to as a human subject): the age is 18-50 years old, and the hearing test shows that the hearing is normal;
d) Listening environment: the room is comfortable and natural, the light is soft and not dim, the ventilation is good, no peculiar smell is generated, the temperature is 22-24 ℃, and the relative humidity is 45-55%;
e) Playback device: the experimental sound sample fragments are generated after the sound samples are randomly sequenced by Matlab, and are transmitted to a headphone equalizer (such as model: HEADlab-compatible binaural headphone equalizers labP 2) by Artemis software through a computer, and then played to a tested person through a moving-coil type high-fidelity stereo headphone (such as model: SENNHEISER HD). During playback, the playback time length, the play interval and the play sequence of the sound samples are controlled by a computer. The sound playback system in the embodiment fully considers the masking effect of the double ears, and can ensure the ideal listening effect of the tested person to the maximum extent.
The annoyance evaluation experiments comprise subjective evaluation experiments, and the testers explain the purposes, flow and notes of the experiments and answer the questions of the testers. Meanwhile, training the tested, randomly selecting 6-8 pairs of sound samples, and requiring the tested to be scored, wherein the test results are not used for subsequent test result processing. During the course of the formal test, the test hears one pair at a time, each pair containing two 5s of sounds, spaced apart by 2s. The first section of sound is a reference sound sample, and the second section of sound is a sample to be evaluated. After listening to each pair of sounds, the test takes 5 seconds to compare the level of annoyance of the second segment of sound with respect to the reference sound sample and score it.
The scored data may need to be processed, for example, to present an invalid score, i.e., to reject an invalid score from the annoyance scores. The rejection of data may be performed according to the following rules: 1) Misjudgment analysis: judging the consistency of multiple evaluation results of the same tested sample; 2) Correlation analysis: judging the correlation between multiple evaluation results of the same tested on different sound samples; 3) And (3) cluster analysis: and judging the consistency of different tested evaluation results.
Step S204, performing coordinate transformation on the second relation curve to obtain a first relation curve.
The annoyance degree variation in this embodiment may be an annoyance degree decrease value, where the manner of coordinate transformation may be: the ordinate and the abscissa in the second relationship curve are converted into the annoyance level decrease value (RASs) and the equivalent sound pressure level change value (Equivalent Level Value, ELV), respectively, to thereby obtain the first relationship curves (RASs to ELV curves).
Referring to a schematic diagram of a second relationship shown in fig. 3, a 1kHz pure tone annoyance versus sound pressure level relationship is shown in fig. 3. For example, a pure tone with a frequency of 1kHz and a sound pressure level of 70dB may be selected as a standard reference sound sample, the sound pressure level of the pure tone is sequentially reduced or increased by 3dB, a sound sample to be measured is generated, subjective evaluation is performed on the sound sample to be measured, and a vexation degree score is obtained, and based on this, a reduction value of the vexation degree in the subjective evaluation experiment is quantized into a reduction value (dB) of the sound pressure level of the standard reference sample. Sound pressure level of the sound sample to be measured: 79dB, 76dB, 73dB, 70dB, 67dB, 64dB, 61dB, 58dB, 55dB, 52dB, 49dB, 46dB, 43dB.
Referring to a schematic diagram of a first relationship shown in fig. 4, the ordinate and the abscissa in the above-mentioned curves may be converted into a reduced annoyance level (RASs) and an equivalent sound pressure level (ELV), respectively, to thereby obtain RASs-ELV curves, i.e., the first relationship.
Step S206, obtaining the regulation sound of the range hood, and determining the annoyance change amount corresponding to the regulation sound; the regulation sound characterizes sound added into noise of the range hood.
In this embodiment, the hearing feeling of one sound (the target sound, generally referred to as the noise of the range hood itself) can be changed by the other sound (the adjusting sound), and the sound after the adjusting sound and the target sound are mixed is called the superposition sound. Therefore, the regulation sound of the range hood can be obtained through the following steps, and the annoyance degree variation corresponding to the regulation sound is calculated and determined: acquiring the regulation sound of the range hood and the target sound of the range hood; the target sound represents noise of the range hood; determining the superposition sound of the range hood based on the regulation sound and the target sound; wherein, the superposition sound represents the sound after the noise of the range hood and the regulation sound are mixed; and determining the annoyance degree variation corresponding to the superimposed sound.
When the superimposed sounds obtained by different regulating sounds are different, the annoyance under the current regulating sound can be obtained through a certain annoyance parameter model. And (3) carrying out an evaluation experiment of the annoyance degree of the superimposed sound of the range hood, and obtaining the annoyance degree reduction value (RASs) of the noise when different regulating sounds are injected. In the experiment, 1kHz and 70dB pure tone are used as reference sound samples; and selecting the noise which needs to be subjected to the annoyance inhibition and the regulating sound to carry out an evaluation experiment of the annoyance degree of the superimposed sound, and carrying out the superposition with different signal to noise ratios to generate a superimposed sound sample. The reference sound sample may be chosen to be a pure tone with a frequency of 1kHz and a sound pressure level of 70 dB. Then, the evaluation experimental data of the annoyance degree of the superimposed sound are processed, and the decrease value (RASs) of the annoyance degree of different regulating sounds to the noise can be obtained.
Specifically, the annoyance corresponding to the target sound and the annoyance corresponding to the superimposed sound of the range hood can be obtained; then, based on the annoyance degree corresponding to the target sound and the annoyance degree corresponding to the superimposed sound, the annoyance degree variation corresponding to the superimposed sound is calculated under a specific rule.
The vexation degree reduction value can be calculated by using a formula, the vexation degree of the sound sample to be measured can be obtained by using a reference scoring method, and the vexation degree variation corresponding to the superimposed sound is calculated by using the following formula: wherein RAS is a superimposed acoustic pairThe corresponding annoyance degree variation quantity, at is the annoyance degree corresponding to the target sound of the range hood, and Ac is the annoyance degree corresponding to the superimposed sound.
For example: the vexation degree of a certain superimposed sound is scored as 4.5, and the vexation degree corresponding to the target sound is 5
Step S208, determining the sound pressure level variation corresponding to the regulating sound based on the vexation degree variation corresponding to the regulating sound and the first sound relation curve.
