I must admit (a bit shamefully) that I was not aware of the fact that volume is on a logarithmic scale and thus following sentence (source) surprised me:
The back seats are closer to 87 dBA, which is good for transporting dogs. A Honda Accord at 70 mph subjects its occupants to around 65 dBA of noise, or about 1/30th the noise level of Cirrus.
However, what actually shocked me, is the last part of the first sentence:
which is good for transporting dogs
If we assume that:
- a Honda Accord at 70 mph (65 dBA) is quite noisy (quite very noisy?),
- 22 dBA (87-65) difference is thirty times more (so quite very, very noisy)
then we may conclude that sound level inside this light aircraft's cockpit offers circumstances that are very not comfortable, if not dangerous, to humans. In fact they actually are dangerous since most sources and organisations, that I reviewed, requires ear protection equipment for environment with sound level at or above 85 dBA.
How can such conditions be good for transporting dogs? Are they much less sensitive to (quite extremely) high noise?
