47- decibel; [dibi] (dB, a way of expressing the magnitude of noise and
vibration)
-------------------------------------------------------------------------------------------------------------
Engineering-Generally, when expressing the 'size' of noise,
vibration, electricity, etc., the unit of 'dB (decibels; dB)' is used. If this
value is large, it means that the value of noise vibration is large. Why were
these units created? You can just say pressure (pa), acceleration (G), and
voltage (V) as they are... The reason is that the unit of dB is easy to
represent the 'range of change for sensory power'. So, strictly speaking,
dB cannot be called a unit because it is a different value depending on how the
standard is set.
Weber-Fechner's law
The change in the amount of human sensation (P) can be best
expressed as the ratio of the amount of change to the standard stimulus amount
(S).
In the above formula, the basic unit is 'Bell', and in order to compensate for the fact that the width of the upper and lower stages is too sparse, 'dB; Decibel' is used by substituting 10 for the constant 'K'. In addition, since it is most suitable to express the change in the a
