How to Operate a Sound Level Meter:
A sound level meter is used to measure the sound pressure level; these devices are primarily used to determine noise pollution levels. Different model sound level meters have different methods of operation though most have more or less the same functionality. They are generally small (hand held), portable and use batteries. The sound level meter will have a microphone, LCD or analog display and function buttons. The amount of function buttons relates to the complexity of the unit but most have a power, hold and minimum and maximum function. Range, time and weighting are other common function buttons- Insert fresh batteries into the sound level meter
- Power the meter on
- Select the "Weighting." There are two types of weighting: A and C. A allows the user to measure sound frequencies between 500 Hz and 10,000 Hz. C allows the user to measure 32 Hz to 10,000 Hz. A is more like a human ear and measures what the ear can hear. C is used to measure mechanical noises, machines and music
- Select a response time. The two options are usually "Slow" or "Fast." Slow measures the average sound levels over time while fast or peak measures the highest sound levels
- Select the range. The range measures different sounds in decibel (dB) ranges. The ranges will depend on the unit. Most have an auto range function that will automatically record all ranges. However, for users who want to measure specific levels they may want to select a range. For example, one range may be between 50 to 100 dB
- Point the device at the sound source after it has been set up. Wait for readings to be recorded. Examine the results
How to Use a Sound Level Meter:
A sound-level meter is a way to measure how loud, in decibels, music is playing. Professional sound engineers often use one to check the volume coming out of a PA at a big stadium show, trying to get the sound to peak at a certain level. In home audio, a sound-pressure level meter can be used to help get the best sound out of your speakers- Insert the battery into the sound-pressure level meter. Point the microphone of the SPLM at the source and take the measurements of the sound coming out of the speakers
- Choose A-weighted on the SPLM when you want to measure specific frequencies, usually between 500Hz and 10,000Hz. Choose C-weighted on the SPLM when you want to get a measurement of the entire frequency range from 32Hz to 10,000Hz. Choose the response time, either fast or slow. Use slow to measure average sound levels and fast to measure peak levels
- Mount the SPLM on a tripod by screwing it into the mount threads on the bottom of the SPLM. Using a tripod will get you the most accurate measurements. Place the tripod at the listening position, generally where your ears are
- Calibrate your speakers by playing pink noise from a test CD, like Stereophile's Test CD (see References for link) through your speakers. You can take measurements on the SPLM to figure out whether you are getting sharp peaks or higher than average sound levels with the speakers placed in different parts of the room. Turn the volume up on your receiver until the SPLM reads 0
- Play the test tones on the Test CD and write down the measurements on the SPLM. Be sure to stand off to the side of the SPLM while doing this to ensure accuracy. Your goal should be to get a reading as close to 0 for each of the test tones. Fiddle with the speaker placement to get this. Some subwoofers, such as Infinity, use this system in conjunction with an equalizer to get the best bass response in your room

07-25-2012- Pros: Easy to use, great value, good response in picking up sound changes, seems to be quite accurate.
- Cons: Power cord- have to attach plug end on your own. Can get slightly confusing over different buttons & modes, slight learning curve.
- Other Thoughts: Used for Health & Safety check on computer server noise level.
