Description
本発明の超低周波音発生装置1(表1に基づく装置)を使用し、簡易家屋を対象とした屋外実験を実施した。
本発明の超低周波音発生装置1を用いて屋外実験を行い、現場試験用の音源としての実用性を検証した。この種の試験のために製作した簡易家屋11から3mはなれた位置に装置1を設置し、家屋11に超低周波音を入射させて家屋11の応答を調査した。図6に、装置1と家屋11の位置関係、および家屋内外における超低周波音の測定位置を示す。
図7(a)には、5Hzの純音を試験音とし、振動板2の変位を徐々に増大させていき、窓ガラスのガタつき音が聞こえ始めた時の振動板2の変位を示す。また、(b)および(c)には、ガラス前面13および家屋内中央14の音圧波形をそれぞれ示す。さらに、(d)には、窓枠に取り付けた振動加速度ピックアップで計測した振動加速度を、(e)には、ガラス中央の変位をレーザー変位計で計測した結果を示す。
Claims (2)
- ボックス状をなす音発生装置の相対する2つの面にそれぞれ圧縮空気によって駆動する振動板を配置し、前記2つの面とは異なる面に音発生装置内に圧力変位を緩和させるダクト等が接続され、逆位相となるように音発生装置内に配置された空圧サーボアクチュエータにて前記2つの振動板が駆動されることを特徴とする超低周波音発生装置。
- 屋外で使用可能な可搬型であることを特徴とする請求項1に記載の超低周波音発生装置。
