Testing sound effect on bacteria growth

[5etemadi]

Hi.
I am doing this project ,Testing sound effect on bacteries growth, when i want to produce some freq. by a small speaker but there is a problem .
I think that small speaker produces UV & that can kill the bacteria . what should i do now ?
thank you for responding ... .

Hi --

Where did you read that small speakers produce UV radiation? I had never heard of that before, and given the way speakers work, I didn't think it was possible. But I could be wrong, and I'd like to research it a bit more before trying to suggest a solution.

Hi,

I have moved this question to the Life Sciences forum since it deals with bacteria growth.

Speakers should not emit UV light as far as I know. If speakers affect bacterial growth, I would assume that it was due to differences in vibration.

Can you tell us a little bit more about what you're having trouble with?
