[pianotech] Hearing Improvement

[Kent Swafford]

The concept is much the same whether you are piano tuning or listening  
to music in a car. Improving the signal to noise ratio is good.  
Improving the signal to noise ratio is something you tend to learn if  
you do audio recording.

To hear the details of music in a car, you want to turn up the music  
to be louder than the road noise. But doing so makes the music  
dangerously loud. Put in hearing protection and both the music _and_  
road noise are attenuated. If the hearing protection is chosen to mask  
most of the road noise, then when you turn the music up, you safely  
hear the music without the road noise. Blaine knows of what he speaks.

Piano tuning is much the same. Mask the environment sounds with  
hearing protection, then pound away on those test blows.
