Is bass damaging to microphones?


Recommended Posts

Posted

So we all know it sounds like a wet fart on video. But I'm wondering.... Is it damaging to the microphone over time? Like having my phone in my pocket or something if I'm bumping on the way to school.

I'm sure it can't be too good for a sensitive little diaphragm like that although you don't really hear too many stories about it.

I do have a sound activated LED controller that I had mounted in my trunk. After a month of use it started acting very flaky and hyper sensitive.

I'm guessing it was from the pressure... :shrug:

Curious to hear other input.

out of my research when it comes to a mic it will distort at high db's. but its not the sound that hurts a mic, its the high spl or a burst of air into it. like lets say your filming steves Tahoe and getting a demo in the front seat. your mic will surely distort but will not damage it. now you walk to the back and put your mic in the port. good possibility you will damage it. microphones these days can handle a lot.

i fucked up my galaxy s3's mics from recording too many videos of 155-160 cars LOL. my stock 14 year old speakers in my car can make my mics distort like crazy now.

The way these work is a little different. There is basically a piece of wire that completes the circuit to turn the light on when it moves enough to touch the side. Eventually it flexes easier from being moved back and forth so many times. At this point it's basically broken in and shouldn't get worse. You should have a sensitivity adjustment knob you can use to adjust for it.

Loud sound CAN damage a microphone, but it would have to be a pretty low quality microphone, or so crazy loud that you would be screwing up your ears pretty bad as well. It probably has more to do with the microphone slapping against the casing than the sound itself. Think about this, did you know you can use earbuds as a microphone? The speaker is so small that sound around it can move it! Now think about how much more it is actually moving when you are playing music through it - and it still works as a microphone afterwards!

It's funny that you mentioned using headphones as a mic. I actually did that some time ago. Turned out pretty good

If anyone has a phone like it: I just got a lumia 920 the other day. Trying to keep it nice since it's the first phone I've got that has a microphone that sounds more like how it should vs. the "oh I recorded it with my phone" sound.

If it really is harmful, I'll probably build a small sealed box for the thing to hold it when I'm bumping
