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 an app to read decibels?

This is smart sound level meter app for Android! ... Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on graph. NOTE: Microphones in most devices are aligned to human voice and the maximum values are limited by the hardware.

How do I calibrate my phone's dB meter?

Calibrating Your Device

1. Get something with a speaker. ...
2. Put the 2 devices at the same distance of the speaker, with the microphones facing the speaker. ...
3. Play the calibration tone and adjust the volume so the Sound Level Meter or the calibrated phone say that the level is between 60-70 dB to use as reference.

What does 52 decibels sound like?

Every sound has a decibel level associated with it. If an item is 52 dB(A), then it has a sound similar in intensity to a electric fan, hair dryer, a running refrigerator and a quiet street. Other common sounds include a blender at 90 dB(A), diesel truck 100 dB(A) and a crying baby can reach 110 dB(A).

How many decibels is too loud?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

What is an acceptable decibel level?

Decibel Level​

Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.

How loud is too loud for neighbors music?

Generally, these rules are not going to help you during the day unless the sound is incredibly excessive (as in hearing damage level). From around 7am – 10pm, your neighbor will not be in violation if the noise is below 60 dB – the equivalent of a vacuum cleaner. But the decibel reading will be from your property line.

How do you calculate sound dB?

Three steps are needed to calculate the decibel level of the sound given above:

1. Find the ratio of the sound intensity to the threshold intensity.
2. Take the logarithm of the ratio.
3. Multiply the ratio by 10.
4. Divide the decibel level by 10.
5. Use that value as the exponent of the ratio.
