About Radio FM 90s
★ Sound Meter (SPL - sound pressure level) is an app which can measure the actual sound level meter with decibels (dB). Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).
★ It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.
★ You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.
★ Remember that it's only a device for fun and please use it as an auxiliary tool.
★ Levels of Noise In decibels (dB) according to American Academy of audiology:
140 dB - gun shots, fireworks
130 dB - jackhammers, ambulance
120 dB - jet planes taking off
110 dB - concerts, car horns
100 dB - snowmobiles
90 dB - power tools
80 dB - Alarm clocks
70 dB - traffic, vacuums
60 dB - normal conversation
50 dB - moderate rainfall
40 dB - quiet library
30 dB - whisper
20 dB - leaves rusting
10 dB – breathing
