Aug 15, 2013· Some other models of sound level meter are designed to work with a separate octave band analyzer that is physically attached to the meter (Figure 20). In either case, the sound level meter microphone operates normally, but the noise signal detected by the microphone is separated into its component frequencies.
Feb 06, 2012· Simulation of Levels of Noise Generated by Local Grinding Machnies Within the Community (A Case Study of Kaduna Metropolis, Nigeria) Ali Haruna*, Mn Agu Department Of Physics Nigerian Defence Academy P.M.B 2109, Kaduna, Nigeria . Abstract. Levels of noise generated from grinding machines were measured. Noise levels as high as 116dB was obtained.
May 14, 2014· The noise levels of bench and pedestal grinders vary with the type of work being performed on the tool. Larger pieces of metal such as 50 mm angle iron will produce much more noise (typically 105 dB(A)) than touching up a drill bit (typically 84 dB(A)). The grade and diameter of the grindstone will also influence the noise level.
grinding wheel, when grinding gears [4]. The diamond grains on the dressing wheel causes undulations on the grinding wheel surface and when grinding the gear, also the gear flank surface will have undulations (waviness). These undulations typically have wavelengths of about 0.5 mm and amplitudes of approximately 4μm.

Loudness, which is the sound power level, becomes ten times higher for each ten decibels increase in sound levels. To better understand this, consider that a whisper registers approximately 30 dB and normal conversation about 50 to 60 dB, while a ringing phone may be 80 dB and a power mower 90.
The increased porosity of the new Norton B45 grinding wheel offers a significant reduction in noise level while grinding hard metals such as Inconel. In Case Study 4, the Norton B45 wheel was shown to reduce the grinding noise by a staggering 23.2 dB. To put this reduction in context, many commercially available ear plugs offer Noise
Grinding medium with long use period, it can be replaced conveniently, or resurfacing welding to repair. 3.Low energy consumption of the system Low noise, environmental protection and saving energy When the machine is starting, there is no fan-effect, low noise and dust-free. If appropriate ventilation at the bottom of the machine, will be better.
Question A noisy grinding machine in a factory produces a sound intensity of 1.00 x 10-5 W/m 2 at a certain location. Calculate (a) the decibel level of this machine at that point and (b) the new intensity level when a second, identical machine is added to the factory. (c) A certain number of additional such machines are put into operation alongside these two machines.
In the evaluation of the wheel wear, the average vibration value for the first grinding minute was significantly higher (P = 0.04) than the value for the second grinding minute for Grinder 1. This was also the case for Grinder 2 for one of the wheels but the difference was not significant.
