Sound Phidget<\/h1>\n

The Sound Phidget measures sound pressure level using a small microphone. This allows you to determine how loud an environment is. This Phidget can also provide sound information about 10 individual frequency bands (32Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz). \u200bThe Sound Phidget returns loudness (sound pressure level) in decibels (symbol: dB)\u200b. A typical vacuum will be around 80dB, whereas a typical Library will be around 40bB.<\/pee> <\/p>\n
