Re: [Phys-l] sound advice

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.
