The hearing mechanism in the inner ear is as much physics as the air waves.
Yes, loudspeakers can output sine waves- listen to Kraftwerk.
Yes, auditory objects can output sine waves - listen to Tibetan bells.
Yes, the ear can hear a sine wave.
You are confusing a sine wave with a pressure wave - basic physics.
You might want to listen to DF96, he knows you know.

Your just talking BS & you & every sensible person knows it
Other way around, I'm afraid - they are pressure waves but who really cares?
You appear not to understand that a sine wave is the description of a function or shape. Sound does not own it!
A point on a spoke (radius) of a rolling wheel describes a sine wave or curve.
If you want to continue to deny Fourier you have a hard task ahead of you.
Your aggressive tone does not help your case.

Merrill,
Er, a lot of people do care Merrill, and as you do not, it indicates a lack of genuine knowledge about a subject that someone like DF96 really does know about. So when he speaks, you should listen.

ToSSorry, I was really saying it is/it isn't was getting to be a boring discussion not worth continuing - who cares was my shorthand for this as I suspect many here don't really care
A sine wave is a useful model, that's all - it doesn't describe the reality of what is impinging on the eardrum which is compression & rarefaction of air molecules - sorry but this is physics 101 & pretty boring to keep discussing it
Apologies tos if I seemed to upset your new BFF
Yes, a function is a model of the world, QED
I've never heard a point on a spoke of a rolling wheel - you might have but I would suggest a DBT if you did to prove to me you can hear this
Funny how pointing out that a sine wave is a model/function is suddenly turned into denial of Fourier
I think I hear a post coming that I should be getting a noble prize
Merrill,
You obviously have yet to master the art of deflection - you need to try harder.

You cannot declare a public discussion as "boring" to your convenience, the only way is to abandon it. Unless your single purpose is to stir the pot.
BTW, what are you doing on this forum? You don't seem to have much fun contributing here, isn't it?
What you are trying to say is that the compression & rarefaction of air molecules which is sound can be modelled as a longitudinal sine wave when the density distribution of the air molecules are mapped.
Still doesn't mean that sound is a sine wave
sound is usefully modelled by sine waves - sound is not composed of sine waves
Do you get the distinction?
Following the same logic, nothing is a sine wave - and nothing is really composed of sine waves.
Sometimes I wonder if you are for real or some sort of trolling bot, programmed to stir the pot on public fora.
Yes, I can declare it boring when I find it boring & suspect that others do too.
Consider it closed & yes, I'm having fun, aren't you?
Fun having your *** kicked 24/7... what do I know about fun.
I see you have a tenuous grasp on reality.
If he means an RF field 20,000V/m, it’s a field strength like the one 1m from an isotropic antenna radiating some 10MW of RF power

And how would you measure that? Rather remotely I would hope! But I am quite sure such a field would cause havoc with any audio gizmo.
My RF test chamber is basically a 50 ohm rectangular transmission line of large enough size that I can put the device under test inside it. It is powered by a 2 watt linear amplifier that goes through a 3 dB amplifier protection pad and into a 50 ohm termination. An AM modulated RF signal generator is manually swept over its' range and the audio output signal is monitored.
I actually have some gear I am working on that passes that test. Almost nothing else does so far based on my limited tests.
