Can all Earth sounds be heard if amplified enough?

AI Thread Summary
Sound waves have a natural frequency range that humans can hear, and while amplification can make some sounds audible, it depends on whether those sounds fall within this range. Even if a fly's movements create pressure differentials in the audible frequency range, they may be drowned out by background noise. Sound reinforcement is essential in large venues to ensure that even faint sounds can be heard by the audience. However, excessive amplification could lead to hearing damage. Ultimately, while amplification can enhance sound perception, practical limitations exist due to environmental noise and the nature of sound waves.

Hello to all,

I've been wondering about sound waves for a while, and here's one question that came up...

Is there a natural limit to sounds being in the audible range... I mean, if we amplify the sounds (edit: the air pressure differences , since I'm not sure they would fall in the sound category) made by a fly 'walking' on some surface, will it be audible ?

Are all Earth sounds audible if amplified enough ?

I know this is a bit crude but I'm sure you get the point ...


Regards,

VE

There is a range of frequencies that we hear, too high of a frequency, and we don't hear it. Dogs hear higher frequencies than us, elephants can hear lower frequencies than us. Kind of just like light, we can't see UV or radio.
 
TR... I'm aware of that but my question still stands, could we hear the fly movin about ?

I'm not wording this question in a proper way, but, I guess what I mean to ask is; if any pressure differential is in the audible frequency range, provided we amplify it enough, we should be able to hear it shouldn't we ?...

Yes. If the frequencies are in the auditory range of the human ear. That's why sound reinforcement is necessary in certain applications, aside from some relatively small amphitheaters that are designed acoustically to disperse sound from the stage to the audience. If I'm on the far side of a 100,000-person capacity stadium, there's no way I could hear someone speaking at normal conversation level or playing an acoustic instrument on a stage without sound reinforcement. Sound reinforcement makes this possible.

If you amplify the sound too much, you could quite possibly never hear anything again!
 
As long as air molecules start to move and hits your eardrum there should exist a possibility of you hearing the fly, but in reality that faint noise will disappear in the 'sea' of other moving molecules hitting your ears.

This one could be cool to read.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
