1.2 安全安装
Sound Meter (SPL - sound pressure level) is an application that allows users to measure sound levels in decibels (dB). Commonly referred to as a sound level meter, decibel meter (dB meter), noise meter, or sound pressure level meter (SPL meter), this app utilizes the device's built-in microphone to provide accurate measurements and a reference point.
The app has been calibrated against various devices to ensure precision when measuring sound levels in decibels.
It is important to note that the built-in microphones are typically optimized for human voice frequencies (300-3400Hz, 40-60dB). Consequently, there are hardware limitations that cap the maximum values that can be recognized, particularly for very loud sounds exceeding 100 dB.
Sound Meter should be considered as a recreational tool and used strictly as an ancillary instrument. It serves to provide entertainment rather than professional-grade measurements.
Below are different levels of noise measured in decibels (dB) for reference:
- 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 rustling
- 10 dB – breathing
