SUBJECTIVE AND OBJECTIVE PROPERTIES OF A SOUND

 Question: What are subjective and objective properties of sound ?

Answer : Subjective properties are basically the properties which can be measured directly. Loudness, pitch (shrillness) and quality(Timbre) of sound are subjective properties. But these properties  are related to the the measurable quantities  called objective properties. 

Objective properties are the properties which can be measured. Intensity,  Amplitude, frequency, wavelength,  time period, intensity, fundamental frequency,  subsidiary frequencies are objective properties. 

Loudness depends on amplitude,  intensity of the sound.

Pitch(shrillness) depends on frequency.

Quality (Timbre) depends on waveform( combination of primary and subsidiary notes).

MECHANICAL ADVANTAGE , VELOCITY RATIO

Which is always constant for a machine of given design: MA or VR ? Ans: VR remains constant for a machine of given design as it depends on the distances moved by the load and effort but MA can vary due to the friction developed between the moving parts of the machine.

What is Regelation?

The melting point of ice is 0°C at normal pressure but when you increase the pressure on ice it melts at the temperature below 0°C( i.e. melting point of ice decreases with pressure). When the pressure applied is released then water formed from ice starts freezing. This phenomenon is called REGELATION.
