Noise pollution is a growing problem, with increased focus placed on reducing it. A New Approach – Using Sound Sensors to Reduce Noise Pollution. Across the world, national and local governments are concerned with noise pollution and its impact on populations, but local regulations and ordinances are sometimes insufficient.The noise level of the Ag/AgCl electrodes is 0.6 nV/rt(Hz) at 1 Hz, which is slightly higher than the noise level of the chopper amplifier with a shorted input of 0.55 nV/rt(Hz) at 1 Hz. The ultralow-noise sensor system is used for marine electric field measurements with high precision during electromagnetic prospecting. Image of a sound sensor. Sound sensors react to changes in the vibrations the pressure of sound waves causes in the environment. A typical soundwave contains a condenser microphone. The microphone converts sound waves into an electric signal. The sound wave produces an electric signal with a proportional frequency. Sensor noise suppression tends to reduce the dimensionality of multichannel data (inflated by sensor-specific noise sources), and thus it may be a useful preprocessing step for methods such as ICA (e.g. Barbati et al., 2004 ). We believe that the method is safe to use as a routine preprocessing step in MEG or …In other words: dBm = 10 log 10 (10/6) + 20 log 10 (V). If you don't even care about the voltage, just the scale, you can just use: dB = 20 log 10 (ADC_value). But if you want the value in dB (A), i.e. normal SOUND intensity decibels, then you'll need to calibrate your microphone against a known decibel meter and sound source.Some sound sensors have digital and analogue outputs (4-pin plug). But this one seems to be digital only (3-pins). So only a sound threshold detector (set with the blue pot). Not possible to use for sound level measurements without hacking. This sensor should be connected to a digital pin. HIGH = noise, LOW = no noise. Leo..
