Common Sources of Noise and Decibel Levels. Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

separate noise criteria and capable of sampling at a 1-second interval over 13 hours. (3) The dosimeters were setup as shown in Table 1. The results from the OSHA settings are used primarily for informational purposes, such as a reference for those who must comply with the OSHA regulations. The areas where noise controls are most needed will be
The aim of this study is to estimate the impact loads delivered to the housing of a hydraulic breaker quantitatively. Striking forces caused vibrations in the equipment housing, which were experimentally measured, and frequency response functions were also found through modal impact experiments. Transfer path analysis (TPA) method of the data quantified the impact

4. To determine the decrease in intensity of the noise away from the source, calculate noise attenuation at 4.5 dB per doubling of distance (Practical Spreading Model). 5. Calculate the potential distance at which the project noise will attenuate to
Among “old-timers”, the Muncie transmission commands a certain degree of respect. Sure, you could get a manual in tons of cars from GM during the 60's and 70's, but the Muncie was the one to have. Saginaw transmissions were cheaper, and worked admirably, but scattering gear oil on the pavement was a scary reality if you pushed them too hard. So for many years
