How can I record low frequency bass neighbor noise? Police say they can't hear it and won't do anything unless I can prove it. I feel the vibrations more than hear them. The sound is below 250Hz and between 78 and 105 dB, C-weighted frequency. All I have is an HP laptop. What do I need to buy? I'm on a very tight budget. This is a health issue, as I can't sleep with their booming noise all the time. Earplugs give me ear infections. My white noise machines running at max (77 dBA) won't mask this sound. My nerves are shot. Headaches for hours even after it (rarely) stops. Bought a Cyber Acoustics "noise canceling computer stand microphone," which is worthless. Bought a Digital Sound Level Meter (40-130dB, A and C weighted, CE AZ8928), but can't convince officers to use it or believe the records I've been keeping. Neighbors said they don't have subwoofers or a big amp, but that's hard to believe with sound this intense. Tried putting rubber mats on the carpet under my bed and even used tires against my bedroom wall to help block the sound, but no luck. Living in a mobile home on 1/4 acre, so no concrete slab. Suspended floor vibrates. Walls and ceiling vibrate. Light bulbs burn out fast. Dishes rattle out of cabinet. Pictures fall off walls. Can't afford to move. Please help!

Can you record a video of the dishes rattling out of the cabinets? Sounds like you ought to file in small claims court.

Sorry, I don't have a video camera. This will probably end up in court, if I can get the police or Code Enforcement to believe me. That's where the sound recording comes in. I filed a complaint with Code Enforcement, but other neighbors won't join in the complaint, probably because of the nature of the offending neighbors, who are usually under the influence of something (alcohol, drugs, etc.) and have a vocabulary mostly limited to short words starting with "F." I'm too old to be afraid, and I also have a 6-foot chain link fence with a locked gate to protect my property (installed because of the offending neighbors), while others in the neighborhood do not. Do you think a video camera would cost less than, say, a Behringer B-1 mic and a used mixer? Could a video camera record these low-frequency sounds? Noise and vibration are the issue. I'm sure the courts wouldn't care about my dishes. I've also considered a security camera, but most of them don't have audio, or can't record low frequencies.

You mean to say that the cops say they cannot hear 105db? That sounds odd. Since you are dealing with the police it might be useful to hire an audio consulting firm to measure the frequency and level of the noise. They will have calibrated equipment that would be legal in court. They can also testify in court to the time as well. Don't know how much this would cost.
