Hi and hello! I´m new to this sight and will make a fool of myself directly. There may be a better thread for this one, so please accept my apology.

A friend om mine thought that perhaps he could record sound with a microphone in a parabolic reflector from a car headlight.
Do you know if sound and light moves in the same way so the sound would be collected to a microphone placed where the lamp would sit in a headlight reflector?
Any answer is interesting for us, thanks in advance,
Karl, Sweden

Hi Karl, welcome to the forum.

Parabolic mics have poor low frequency response. The smaller the diameter of the dish, the higher the frequency response cut-off. A typical headlight would have very poor response below about 1500 Hz. It would probably be okay to record bats, otherwise not so great.
