哦~~~我知你講咩喇，我之前都有類似嘅，用一格入牆櫃作貓廁所.
係入面加裝抽氣扇直出屋外，真係搞得掂啲塵呀味呀之類.  不過抽氣扇好快污糟，可能係你講呢隻，換好過洗.  下次我要裝隻Panasonic嘅廁所用型號先得...

係好好好嘈!!
一般改裝跑車，條死氣喉排氣聲都未必有120db...
and you have 120db X 2 喺屋企

SO FAR冇人投訴, 所以真係好好用,  如果我D衰仔好似ONON D雀咁靜咁乖, 我邊洗用咁多錢去解決問題丫

其實有更好嘅滅音方法, 好似上星期六, 發仔响九展, 街坊話一位好好嘅雀友同佢按摩左四個鐘, 所以當日發仔冇叫, 但九展第一日, 冇人摸佢, 佢就成功擊倒一班有意養鸚鵡嘅市民內心嘅熱 ...

嗰日I was there，發仔龍吟左幾聲，由如寶刀出肖~~~
