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).
