Sound Meter - Noise detector 1.25.21

Sound meters work efficiently to measure environmental noise levels, including acoustics. A sound detector is commonly known as an SPL meter or decibel meter (dB meter). These devices help to easily detect excessively loud or too low sound levels, contributing to the preservation of hearing functionality. A sound test app or a loudness meter serves as a valuable noise measurement tool through a sound level meter or a sound analyzer app, which functions as an audio spectrum analyzer, providing insights into environmental noise.

Decibel meters, also referred to as octave and sound pressure meters, noise detectors, and noise detection technology, utilize mobile microphones to gauge ambient noise levels in decibels. The real-time decibel measurements and curves are displayed during operation. These tools are user-friendly and enable the measurement of the surrounding noise environment effectively.

A dB noise detector utilizes the phone's microphone for decibel-based environmental noise measurements. The dB values provided by this decibel meter may vary compared to actual sound meters or audio tools. Users can conduct noise measurements conveniently using their phones, helping to equate loud sounds, which can be detrimental to physical health and hearing functionality. By utilizing noise meters or decibel meters for measuring environmental noise, modern sound sources and sound levels can be effectively monitored.

Notes:

• Most Android device microphones are calibrated for human voice meters in sonometers and have maximum value limits. Extremely loud sounds above approximately 90 dB may not be accurately recognized by most devices. It's advised to use these tools as auxiliary aids. For precise dB values, consider using professional sound level meters.

Levels of Noise in Decibels (dB) according to the American Academy of Audiology:

• 140 dB - Gunshot sounds (dB navigator)
• 130 dB - Ambulance sirens (modern sounds)
• 120 dB - Jet planes take-off (loudness meter)
• 110 dB – Concerts (Hz meter), Car horns
• 100 dB – Snowmobiles (sound meter)
• 90 dB - Power tools (audio meter)
• 80 dB - Alarm clocks
• 70 dB – Traffic noise, Vacuum cleaners
• 60 dB - Normal conversation (decibel scale)
• 50 dB - Moderate rainfall sounds
• 40 dB - Quiet library environment
• 30 dB - Whispering sounds
• 20 dB - Rustling leaves in the environment
• 10 dB – Breathing sounds
