Abstract
Lärmpegeldetektor, bestehend aus einem zwei- oder mehrstufigen Verstärker, weiter bestehend aus einer oder mehreren LED und bestehend aus einer Stromquelle, dadurch gekennzeichnet, dass die Vorrichtung eine Schaltung für eine visuell einstellbare Schallpegelanzeige zur Kontrolle für überschreitenden Lärmpegel ist.Noise detector consisting of a two- or multi-stage amplifier, continue consisting of one or more LEDs and consisting of a power source, characterized in that the device is a circuit for a visually adjustable sound level indicator is to control for exceeding noise level.
Description
Die Erfindung betrifft einen Lärmdetektor, ausgestattet mit einer visuellen Schallpegelanzeige, bestehend aus oder mehreren LED und einer Stromquelle.The Invention relates to a noise detector, equipped with a visual sound level indicator consisting of or more LED and a power source.
Nächtlicher Fluglärm oder das Wohnen in der Nähe von sehr befahrenden Straßen erzeugen Bluthochdruck und können Herz- und Kreislauferkrankungen auslösen.Night aircraft noise or living nearby from very busy roads generate high blood pressure and can Cause cardiovascular diseases.
Aufgabe der Erfindung ist es, einen Lärmpegeldetektor mit einer visuellen Schallpegelanzeige zur Kontrolle für zu hohen Lärm herzustellen und durch eine einstellbare Lärmpegelanzeige mit einer oder mehreren LED auszustatten, um einen überschrittenen Lärmpegel anzuzeigen.task The invention is a noise level detector with a visual sound level indicator for checking too high Make noise and by an adjustable noise level indicator equipped with one or more LED to exceed one noise level display.
Die hier angezeigte Erfindung sollte vorzugsweise eine mobiler Lärmpegeldetektor und durch seine Ausgestaltung flexibel einsetzbar sein. In geschlossenen Räumlichkeiten kann es an einem Fenster oder in der Nähe aufgehängt oder aufgestellt werden.The The invention presented herein should preferably be a mobile noise level detector and be flexible due to its design. In closed premises it can be hung or placed near a window or nearby.
Die Schaltung bildet mit zwei OPs einen zweistufigen Verstärker.The Circuit forms with two OPs a two-stage amplifier.
Vorzugsweise solle das Schallsignal vom Piezosensor in ein elektrisches Signal umgewandelt werden.Preferably should the sound signal from the piezoelectric sensor into an electrical signal being transformed.
Die Lärmpegelanzeiger sollte mit einer oder vorzugsweise mit mehreren farblich verschiedenen Dioden ausgestattet sein.The noise level indicator should be one or preferably with several different colors Diodes be equipped.
Das IC1A bildet einen 1-stufigen Verstärker, der bei Erreichen eines bestimmten Eingangspegels eine Ausgangsspannung erzeugt, die ausreicht, um die LED1 (die Farbe rot) leuchten zu lassen. Die Verstärkung, also der Wert bei dem die LED1 beginnt zu leuchten, lässt sich über das Poti R1 einstellen.The IC1A forms a 1-stage amplifier, which when reaching a certain input level generates an output voltage that is sufficient to light the LED1 (the color red). The reinforcement, so the value at which the LED1 starts to light can be adjusted via the R1 potentiometer.
Das IC1B bildet eine nachgeschaltete Verstärkerstufe, die den Signalpegel weiter, wie IC1A verstärkt, das bedeutet, der Ausgangspegel bringt die LED2 (z.B. die Farbe gelb) deutlich früher zum Leuchten als die LED1 und bildet somit die Anzeige für kleinere Schallpegel.The IC1B forms a downstream amplifier stage that controls the signal level continue, as IC1A reinforces, the means the output level brings the LED2 (for example the color yellow) much earlier to light up as the LED1, thus forming the indicator for smaller ones Sound.
Der Empfindlichkeit der Einstellungen sind nur nach oben Grenzen gesetzt.Of the Sensitivity of the settings are only set to upper limits.
Die Versorgungsspannung der Schaltung kann bei 6V–12V liegen.The Supply voltage of the circuit can be at 6V-12V.
Der Versorgungsstrom liegt bei ca. 300 μA wenn keine LED leuchtet.Of the Supply current is approx. 300 μA when no LED is lit.
Die Lebensdauer kann somit z.B. bei Betrieb an eine 9V-Blockbatterie im Bereich von 30–60 Tagen liegen. Je nach eingesetzten Bauteilen kann mit einer Lithium-Knopfzelle eine Lebensdauer von bis zu 90 Tagen erreicht werden.The Life span can thus be e.g. when operated on a 9V block battery in the range of 30-60 Days lie. Depending on the components used, a lithium button cell can be used a life of up to 90 days can be achieved.
Vorzugsweise sollte die Schallmessung mit einem Impulszähler bzw. Controler ausgestattet sein, um die Nachweisbarkeit von Lärmüberschreitungen dokumentieren zu können.Preferably The sound measurement should be equipped with a pulse counter or controller be to document the detectability of noise exceedances to be able to.
Vorzugsweise sollte das Schallmessgerät mit einer Tonanzeige ausgestattet sein.Preferably should the sound meter be equipped with a sound display.
