The sound of Mach 1 is around 130 dB.
80 dB is 10 times louder than 70 dB, and 70 dB is 10 times louder than 60 dB, and so on. Therefore, 80 dB is 1000 times louder than 40 dB.
db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02
A 90 dB sound is 1,000 times more intense than a 60 dB sound. This is because the decibel scale is logarithmic, with every 10 dB increase representing a tenfold increase in intensity.
A normal conversation at 60 dB is 1,000 times more intense than a close whisper at 20 dB. This difference is due to the logarithmic nature of the dB scale, where each 10 dB increase represents a tenfold increase in intensity.
DB701 is lighter (They are German Railway Colours - Deutsche Bahn = DB)
Mach 1 is about 761.2 mph
about 720. or 1100ft/sec
mach 1 = 340.29 m / s

How many db is produced in a disco
2 db's.

That depends on you. If you want, you can say 1 watt should be 0 dB.
