Moshe writes that if a sound is audible in an adjoining room, it constitutes hashmoas kol. I do not recall any explicit definition of this in the Gemara, and it appears to be a subjective concept. For example, if one lives alone, it could be argued that the sound would need to be audible outside the house to qualify. On the other hand, one could equally argue that even within that house it constitutes a zilusa de-Shabbos to operate loud implements.</span></p>

A related issue arises today with respect to robotic vacuum cleaners. As I understand it, they generate the most noise when expelling dust into the receptacle. I am not aware of any posek who has defined hashmoas kol in terms of decibel levels.</span></p><div><span style="font-kerning: none;"><br></span></div></div></body></html>
