There is no similarity. Loudness has to do with sound pressure amplitude coming from the sound source. Pitch has to do with the frequency of the tone the sound source is making. Loudness cannot be pitch.
Pitch describes the frequency of a sound.
No. A sound's pitch depends on the frequency of the wave.
Loudness and pitch are properties of sound which can be determined by looking at the sound wave. You have a high pitch when the frequency of the wave increases or the wavelenght (lambda) decreases. When the amplitude increases the loudness of the wave increases as well.
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
LOUDNESS
Loudness depends on the amplitude. square of amplitude is proportional to the loudness. Pitch is decided by the frequency. One can sing at higher pitch but at lower voice.
The loudness of a sound depends on the amount of energy it takes to make the sound and the distance from the source of the sound.
Amplitude is the primary factor in determining the 'loudness' of a sound wave.
Pitch does not determine loudness, and loudness does not determine pitch. Loudness is the measure of sound pressure (dB), while pitch is the frequency at which an object vibrates. You cannot say any pitch is louder than another, because pitch and sound intensity are completely independent of each other.
The amplitude of the sound waves in the medium.
