Arduino Sound Sensor Decibel. Arduino Decibel Meter This project will help you to monitor the noise or sound level by measuring sound pressure.
Arduino Sound Sensor Module Sound Sensor With Arduino Code Arduino Project Hub from Develop your Arduino code in the cloud and build smart IoT projects – Arduino
Decibel Meter using Sound Module & Arduino with LCD Display has been designed specifically for detecting the level of sound produced from any source and its intensity as well The LCD panel directly displays the information about the sound level in numbers The sound is distinguished as low medium and highlevel sound on the basis of number Video Duration 4 min.

Let’s say your real SPL meter reads 80dB when the Arduino reads 270 270 is your reference analog reading A REF at 80dB SPL Now the volume increases and we get a new analog reading of A = 540 and we can calculate the dB difference or change dB = 20 log(A/A REF) = 20 log (540/270) = +6dB That’s 6dB higher than your reference so we have 86dB SPL.
Decibel Meter using Sound Module & Arduino with LCD Display
Overview Arduino Decibel Meter using Sound Sensor You might have seen the decibel meter available in the market that generally measures the sound intensity and level The sound loudness is measured in terms of decibel Different soundproducing medium ranging from airplanes to human whisper has a certain level of sound loudness expressed in decibel.
How to convert sound sensor output reading to decibel value
Arduino Sound Level Meter Measure Sound/Noise Level in dB
Arduino Decibel Meter Instructables
Measure Sound/Noise Level in dB with Microphone and Arduino Noise pollution has really started to gain importance due to high population density A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise Loudness or sound levels are commonly measured in decibel (dB) we have some instruments which could measure the sound signals in dB but these meters are slightly expensive and sadly we do not have an out of box sensor.
