Mach is a unit of speed, specifically the ratio of an object's speed to the speed of sound in the surrounding medium. It is not directly measured in decibels, which are used to quantify sound intensity or pressure. However, when an object travels at Mach 1, it creates a shock wave that can generate sound levels exceeding 130 decibels, depending on various factors such as altitude and environmental conditions. Therefore, while Mach itself does not have a decibel value, its effects can produce very high sound levels.
in what
•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons or a stereo can make up to 80 decibels. Volume is measured in decibels. So Frequency is measured in hertz

Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
The usual symbol for decibels is dB.
Sound does not travel in a vacuum. Mach"s constant is 760 miles per hour, but in an airless environment, like the Moon, mach speeds would not apply.
20 decibels
207 decibels.
70-100 decibels
in what
20 to 50 decibels (dB).
85 decibels maximum.
130 decibels -140 decibels close up maybe louder though
Roughly 150-160 decibels.
50 phons (decibels) is equivalent to 2 sones.

a plane has 15000 decibels, there are lots maybe upto 2000000
