7 Range Sound Level Audio Noise Meter Decible DB New with Analog Display Measurment DB
This is a Brand New Sound Level Pressure Meter which is useful for measuring sound intensity, determining speaker efficency or developing quick frequency response plots for loudspeakers. Power is supplied by a 9-volt battery, so the meter is completely portable.
To create quick frequency response plots, use an Audio Test CD and read the sound pressure directly from the meter. You can search for a free Audio Test CD on the Interner.
For more detailed plots, you can use a wide variety of commerical and free software. You can also search for a Free Frequency Response Plotter Software with built in corrections for the meter on the Internet.
For more accurate results while testing loudspeakers, it is best to do the measurements outdoors in a quiet and spacious area.
Your sound level meter is an extremely versatile device for measuring sound intensity in just about any acoustic environment-loud or soft: high-pitched, lowpitched, or broad-band; intermittent or continuous. You can use it to measure noise levels in factories, schools, offices, and airports, or to check acoustics of studios, auditoriums, and home theater installations.
Your meter features a large, easy-to-read indicator for taking quick measurements anywhere. Power is supplied by a 9-volt rectangular battery, so the meter is completely portable.
