Re: melodious sound generator

I read in sci.electronics.design that Spehro Pefhany <speffSNIP@xxxxxxxxxxxxxxxxxxxxxxx> wrote (in <g2lbh1t766m6j2bahc5j95f2hbne9c6boe@xxxxxxx>) about 'melodious sound generator', on Wed, 31 Aug 2005:

That's interesting. I find the little ultra-short pings of (3-4kHz?) noise from my execrable Siemens phone handsets (as the rechargeable battery is dying) almost impossible to locate. The echoes probably don't help.

The echoes are the main cause of the confusion. In an anechoic room, it's much easier to locate the sound.
