Bearing Vibration Standards

WE SEEM to accept noise in machinery as inevitable. If our forefathers came back to earth, apart from the frightening speed of everything, methods of transport and a hundred and one unbelievable ‘improvements’ to civilised living, we think it is the noise that they would find most difficult to withstand. Noise of transport, noise in a factory, and the apparently unconcerned attitude of those who are used to it. Modern medical science is now finding out that ears can be damaged by excessive noise, and certainly a great deal of it can be reduced if proper care is taken in machine design and maintenance. We believe that there is a society formed to consider these problems. Jet aircraft have roused many people to consider noise, but this is only one item.
