Re: Sound Level Meters

Rebecca,

I can suggest you Sound Level Meter by 01dB-Metravib :http://solo.01db-metravib.com/

Largely used by professional acoustic consultants for noise impact measurments (calibration is made with a "calibrator"). 01 dB has an office in the USA (see on the website).

Bruel & Kjaer also provide similar equipment.

Hope this helps

I need to perform some sound level readings at an industrial facility and am looking for a good logging octave-band recorder. I'd appreciate recommendations.

The equipment must be capable of handling the following bands 20-75, 75-150, 150-300, 300-600, 600-1200, 1200-2400, 2400-4800, and 4800 and above. The equipment must ALSO be compliant with the ANSI standards for Sound Level Meter Sl4-1971 and for Octave Band Filter Sets SL11-1966, R1971. I realize these standards are out of date, but those are the ones I have to be sure the equipment complies with, so if anyone knows how those earlier standards relate to ANSI Type 1, 2 etc. it would be greatly appreciated.

Also, recommendations for companies in the USA who rent such equipment would be greatly appreciated (as in, if you had a particularly GOOD or BAD experience with a certain company, this would be helpful to know).

A final question is with regard to calibration of the equipment -- are they self-calibrating, or is there a calibration test-set that one can purchase to ensure the equipment is in spec.

Thanks in advance for any information that folks can provide.
