Research points to SoundMeter as the best sound level meter app available on any mobile platform:The evidence suggests that for A-weighted data, SoundMeter is the app best suited for occupational and general purpose noise measurements. In addition to having the smallest mean difference for the A-weighted data, SoundMeter had the narrowest distribution of differences. Contact a qualified acoustical testing laboratory for information regarding standards certification.

Vibration

Vibration is a true vibration spectrum analyzer using the built in accelerometers and gyroscope inside the iPod Touch and the iPhone and starting with version 3.x it can sample the built in microphone and the Digiducer professional quality external USB accelerometer. It acquires and displays time series data, optionally removes DC bias, applies a Hamming window and performs an FFT on each channel to produce frequency spectra. Please use the email links in the program to request new features and report any problems.
