発電機防音ボックス
自作の発電機防音ボックスです。エコ運転時の騒音は、アスファルト上の2mの距離で46.5dB〜47.5dB！風が吹いたり車が通ったりすると、その音で2mの距離でも、発電機からの音はほぼ聞こえませんので、かなりの消音化が出来ました！再生中に聞こえるシャーという音は車の通る音です。こだわりはボックスに余計な出っ張りを作らず、極力スマートな見た目にした事です。重量もボックス単体で22~23キロと軽量です。 http://blogs.yahoo.co.jp/ponmon2011/1... http://blogs.yahoo.co.jp/ponmon2011/1... http://blogs.yahoo.co.jp/ponmon2011/1... http://blogs.yahoo.co.jp/ponmon2011/1...
