So in this project we will use a normalElectret Condenser microphone with Arduinoand try measuring the sound or noise pollution level in dB as close as possible to the actual value. We will use a normal amplifier circuit to amplify the sound signals and feed it to Arduino in which we will...
Sound pressure p Pa | Sound level Lp dB (SPL) | Sound level LI dB (SIL) Sound intensity I W/m2 | Sound propagation in air | Fill in the gray top box and click on the calculation button. 1 Pa = 1 pascal = 1 N/m2. The atmospheric pressure is not the same as the sound pres...

Pressure data from all six hydrophones were averaged, then converted to dB to provide a single received SPL (dB re 1µPa) per source position, representative of the sound level in the centre of the hydrophone array. Power spectral density (PSD) analysis was carried out on the mean ...
It can be used for multifaceted analysis of complex sound characteristics and trends in frequency of occurrence of any sound source. # Measurement functions Main (Leq): Sound level measurement (real time display) - Sound level measurement (dB): Leq (equivalent sound level), Min (minimum value)...
