Sounds are reported as detected with the dBA of the sound level meter. A-weighted sound levels emphasize the middle frequency (i.e., middle pitched – around 1,000 Hertz sounds) and de-emphasize lower and higher frequency sounds. The dBA most closely approximates how the human ear responds to sound at various frequencies. Because the sounds in the environment vary with time, they,Noise and Impact Hammers - American Piledriving,sound level is expressed in decibels (dB). More advanced devices are being used to determine the type of sound coming from impact pile hammers. Photo by Craig Wood. This meter totals all noise. The two types of noise we are interested in: 1) Point Source 2) Line source. Point source An example of a point source is sound coming from a single point, such as the noise coming from the anvil,7.0 Construction Noise Impact Assessment.,1.
