Re: [Phys-l] sound advice

[Bernard Cleyet <bernardcleyet@redshift.com>]

For something rather different:  decouple a speaker w/ an appropriate  
value resistor*  from an audio oscillator.  Find the resonance(s).   
Usually audible, but measuring the PD of the speaker will quantify  
it.   One may vary the conditions much, e.g gluing a weight (solder)  
to the cone, placing in a baffle, in a box, in a box w/ sound  
absorbent, etc.


* especially necessary w/ the modern 50 ohm Z generators or using a  
power amp.

bc did this much in HS.
