Noise Level Meter - Nox

Nox turns your phone into a decibel meter, sound meter and noise meter. Point it at any sound and see the noise level in decibels (dB) live, with minimum, average and maximum values.

Use Nox to check how loud a room, office, classroom, street or concert is, find out whether your neighbors are too noisy, test a speaker, or compare the sound level of different places.
