BISOPE series 57- decibel; DB (dB, a way to express the level of noise and vibration)

-------------------------------------------------------------------------------------------------------------

In engineering - generally, the unit of ‘dB (decibel; dB)’ is used to express the ‘size’ of noise, vibration, electricity, etc. If this value is large, it means that the value of noise and vibration is large. Why were these units created? You can just call them pressure (pa), acceleration (G), and voltage (V) as they are... The reason is that the unit dB easily represents the 'range of change in sensation.' So, strictly speaking, dB cannot be said to be a unit because it is a value that varies depending on how the standard is set.

 

Weber-Fechner's law

 

The change in human sensory quantity (P) can be best expressed as the ratio of the change amount to the reference stimulation quantity (S).
