Well, maybe you need one of these decibel meters to determine if the sound level in your space is harmful to your hearing. Some atmospheric attenuation also occurs in fog and precipitation, in dust in air, and at frequencies below 10 Hz due to electromagnetic radiation of moist air molecules. ASTER can collect data in 14 spectral bands from the visible to the thermal infrared. Note that you can't just use an ADC to meaningfully measure sound pressure. If there are reflective surfaces in the sound field, then reflected sounds will add to the directed sound and you will get more sound at a field location than the inverse square law predicts. Although you might not see the meter reader, we attempt to read each meter once a month. Filtering it out offers dramatic improvements!
