Sonic Scan

       iOS iPhone

Displays sound pressure level [decibel] and frequency [Hertz] of sound in your environment.

Measure noise exposure in residential areas, at work, inside cars (compare cars), in bed- and livingrooms, near airports, discos, party noise, traffic noise, ...

A-weighting for sound pressure level (the most commonly used weighting used to emphasize frequencies around 3–6 kHz where the human ear is most sensitive, while attenuating very high and very low frequencies to which the ear is insensitive).

Support for upside down device orientation (mic towards sound source).

Decibel meter calibration (shift and scale).

Sound pressure ranges from approx. 35 up to 105 decibels.

The real time frequency value displayed shows zero-crossings per second.

Even though Sonic Scan passed tests with professional equipment, Sonic Scan cannot replace professional equipment and should be used for entertainment purposes only.
