Abstract
Description
nλ=2b sin(θ)
ここで、nは整数、λは入射する音波の波長、bは格子定数(即ち、隣接する中空円筒状要素110間の距離)、及びθは部屋間仕切り100に対する音波の入射角である。従って、所望の周波数における減衰は格子定数bを適切に選択することによって達成され得る。オフィス環境に関しては、減衰させる対象となる音は会話及びプリンタノイズなどの低周波ノイズである。これらの音はそれらのエネルギーの殆どを300Hz乃至3000Hzの周波数範囲内に有する。従って、格子定数bは、6cmよりも大きく、20cmよりも小さいことが好ましい場合がある。20cmという格子定数bのブラッグギャップは850Hzの周辺で現れるが、より低い周波数の減衰は、以下に記載されるように、共鳴などの他の効果と併せて達成され得る。
