Where in Sacramento can you rent a decibel meter?
Do not rent a sound pressure level meter. Buy it at Radio Shack for 50 dollars. Scroll down to related links and look at "Sound pressure level meter".
How would you measure the sound level increase due to the addition of multiple fans in a computer case?
A decibel meter can be purchased in a high end electronic store and there is a decibel meter app available for smart phones. If you wish to measure the amount of sound coming from your vacuum cleaner and you have a smart phone, then I would recommend using the app because it is much cheaper than the scientific tool.
The frequency of sound is measured by a frequency meter. The volume is measured using a decibel meter Sound Level Meter The sound level meter is the basic measuring instrument for noise exposures. It consists of a microphone, a frequency selective amplifier, and an indicator. At a minimum, it measures sound level in dB SPL. An integrating function may be included to automate the calculation of the TWA or the noise dose. Sound is measured…
Decibel with the abbreviation dB is equal to one-tenth of a bel, after Alexander Graham Bell. It is a measuring system first used in telephony in 1929. It is a logarithmic unit of measurement that expresses the magnitude of a physical quantity, usually power or intensity, relative to a specified or implied reference level. Since it expresses a ratio of two quantities with the same unit, it is a dimensionless unit. The inventor of the…
What is the decibel of someone trumpeting? Use a sound pressure level meter (SPL) and measure the dBs. Don't forget to notice the distance of the measuring point from the trumpet. Because doubling the distance shows a level going 6 dB down. Scroll down to related links and look at "How to calculate dB?"
