Wheeze, howling and buzz noises of machines represent a common problem, especially with gearboxes. Due to these tonal components in the overall sound, the sound quality is reduced significantly.
There are many acoustic analyses, which have especially been developed for the evaluation of these acoustic phenomena.
This tutorial will show you how these analyses work and when they can be used best.
The following analyses are explained by means of practical noise examples:
• Tone to Noise Ratio
• Tonality DIN 45681
• Specific Prominence Ratio
• Specific Tonality (Hearing Model)
