SoundMeter turns the iPhone into a handheld sound level meter

August 12, 2008 in Music (E)

[] Santaquin, Utah - By popular demand, Faber Acoustical's latest iPhone app, SoundMeter, turns the iPhone into a handheld sound level meter. The iPhone's built-in and headset microphones exhibit a frequency response which is flat enough to make them suitable for basic sound level measurements.

SoundMeter measures average sound levels with fast, slow, and impulse time weightings. Peak, maximum, and equivalent sound levels are also available. All sound levels may be measured with Flat, A, or C frequency weighting.

Since SoundMeter has not been shown to meet ANSI or IEC standards for precision sound level meters, it is an excellent alternative to other inexpensive handheld meters for home or hobbyist use. Due to bandwidth and frequency response limitations, SoundMeter is not recommended for use with the built-in microphone of first-generation iPhones. For best results, SoundMeter should be calibrated before use.

Pricing and Availability:
SoundMeter is now available for download on the iPhone App Store for $19.99 USD. More information on SoundMeter can be found at Faber Acoustical's website.
