 · To raise the pitch of the note vented by that tonehole by 10 cents would require removing (filing) 20% or .0375" of material leaving a height of .150" - roughly 5/32". A "typical" amount of material removed when flattening toneholes that have been made as level as possible by "mechanical" means is around .001" which is removed from only the highest areas around the circumference.

Electrical and Mechanical Noise in Motors

In measuring a mechanical noise, the noise level (loudness) is physically measured by a noise meter. The calculation will be made to convert to JIS-A characteristics ( dB with RMS ). In the measurement, the following factors in/out of the motors may affect the test result, therefore should be specified strictly before the measurement.
