Can I measure noise level with Android?
With a free app and your Android phone, you can turn your phone into a noise meter and find out. Download Sound Meter from the Android Market and launch the app. It starts right up to the sound meter and measures the minimum, mean, and maximum ambient sound levels in decibels (dB).
Is there a noise detector app?
Sound Meter This Android app gives you the circular gauge other apps use, a color-changing screen when noise exceeds safe levels, and a running line graph. It can be calibrated and features an extensive menu of options.
Is there a free app to measure noise levels?
Sound Meter (Android-Free) Utilizing a graphic interface to show reference, the Sound Meter app uses your devices embedded microphone to measure the level of noise in decibels.
How accurate are phone dB meters?
The tests also compared results for i-Phones and Android phones. OSHA requires noise measurement instruments to have an accuracy of +/- 2 decibels (dB). For unweighted sound level measurements, NoiSee, SoundMeter and SPLnFFT had mean differences within the +/- 2dB of the reference measurement.
Can I measure sound decibels on my phone?
Thanks to modern technology, your smartphone can measure decibels to determine if your environment exposes you to harmful noises that may cause permanent or temporary noise-induced hearing loss (NIHL).
How can I test my noise level?
To measure decibels, download a mobile decibel-reading app, like Sound Level Meter or Decibel Meter. You can also measure decibels using computer programs like Audacity or Decibel reader. Another option is to use a profession decibel meter, which can give you a very accurate decibel reading.
How accurate are Android decibel apps?
They show that one of the apps tested – SLA Lite – is within ±1 dB of true noise levels across four different reference conditions. The results also show that there is a significant relationship between phone age and its ability to measure noise accurately.
How loud is breathing in dB?
about 10 dB
Sound is measured in decibels (dB). For reference, normal breathing is about 10 dB, a whisper or rustling leaves 20 dB, and conversation at home are around 50 dB. A washing machine registers roughly at 70 dB, and a lawnmower is around 90 dB. Very loud sounds include fireworks (150 dB) or shotgun blast (170 dB).
Is there an app to measure occupational noise exposure?
NIOSH hearing loss researchers collaborated with an app developer, EA LAB, to create an iOS based sound level meter app that measures and characterizes occupational noise exposure similar to professional instruments.
How do I measure noise on my Android phone?
With a free app and your Android phone, you can turn your phone into a noise meter and find out. Download Sound Meter from the Android Market and launch the app. It starts right up to the sound meter and measures the minimum, mean, and maximum ambient sound levels in decibels (dB).
What are the metrics in the noise monitoring app?
The app also reports the main metrics that are of importance for proper occupational noise measurements – mainly the run time (total time), the A-weighted Equivalent Sound Level (LAeq), the Maximum Level measured during the current run time, the C-weighted Peak Sound Pressure Level (LCpeak), the Time-Weighted Average (TWA) and Dose.
Can the app provide an exact geospatial location of the noise?
If location services are enabled, the app can utilize the GPS feature to provide an exact geospatial location of the noise measurement. Note: Professional sound level meters must comply with a host of acoustical and electrical tests to meet national and international standards.
