RMS meters approximate the way your ear perceives sound levels; your ear will typically not perceive sharp peaks to be as loud as they really are. A peak meter is a type of visual measuring instrument that indicates the instantaneous level of an audio signal that is passing through it (a sound level meter).
Also know, what does RMS mean on multimeters?
RMS is the Root Mean Square, or effective heating value of any ac voltage or current waveform. RMS is the equivalent DC heating value of an AC waveform. A true-rms device is one of three tools that can measure alternating current (ac) or ac voltage: 1. True-rms digital multimeters (or clamp meter)
What does RMS voltage stand for?
What does RMS measure?
The RMS value is the effective value of a varying voltage or current. It is the equivalent steady DC (constant) value which gives the same effect. For example, a lamp connected to a 6V RMS AC supply will shine with the same brightness when connected to a steady 6V DC supply.
