My son plans to have some of his students study the effects of urbanization on frog populations next semester. They have NSF funding and are trying to determine what method(s) they will use to measure the sound pressure of jet airliner noise in various locations. Can the group give us some advice on types of dB meters and suggestions on what to purchase. Are the mics in dB meters typically omni or cardioid? Gene |
