Membrane Absorbers

Postby witchking on Tue Oct 20, 2015 6:43 am

Hello, new member here.

I was reading the membrane absorbers explanation page and the caption underneath figure 1 says "Sound energy strikes membrane, membrane flexes, dissipating energy as heat."

I was just wondering if after extended periods of recording (perhaps a bass amplifier), the membranes actually dissipate enough energy to feel or change the temperature of the room. I am going to guess that the answer is no, but I figured it would be worth asking.

Thanks!

Will

in your scenario, the membranes probably do not produce nearly as much heat as the bass amp, the voice coils in the cab, the lights, and the people in the room.

that's what AC is for.

No, we're talking tiny, tiny amounts of heat spread out over a large area.

Try heating up a glass of water by shouting at it.

______

Membranes absorb bass, so the sound energy or turning rate is relatively low for even significant amplitude.

Try heating up a piece of plywood by bending it back and forth.

The way to think of its function, really, is not as heating per se, but the dissipation of sound energy via internal friction or "damping ratio".

______

Friction can cause heat, such as on car or bicycle brakes, but in acoustics terms it is not generally thought to have any measurable influence on temperature. It would not be possible to analyse the performance of an absorber with a thermometer or infrared camera.

Indeed, the bass player probably produce more heat than the resonator and the amp itself :smt004 :mrgreen: :mrgreen: the amount of heat produced by the resonator is minimal as we are talking about air particles friction with the absorbing material.
Have any of you guys tried the acoustic fields products? specifically the diaphragmatic absorber with carbon technology? I'm thinking of buying their kits.

There are no jobs in engineering and production. The number of graduates from audio programs outweighs the number of available jobs in the "industry" by orders of magnitude.
