properties of sound

Properties of Sound

• Property 1: Pitch/Frequency. The perception of frequency of sound by human ear within the range of human hearing is called the pitch.
• Property 2: Amplitude/Loudness. The amplitude of the sound waves determines its loudness.
• Property 3: Speed.
• Property 4: Reflection of sound.
• Property 5: Timbre.

4 main properties of musical sounds: • • rhythm/duration - when to play the notes amplitude/loudness - how loud to play the notes pitch - which notes to play timbre/tone color - sound quality • which instruments are playing?

Muscles have four basic properties:

• Excitability: Ability of muscle to respond to stimuli.
• Contractility: Ability of muscle to contract or shorten its size.
• Extensibility: Ability of muscle to stretch.
• Elasticity: Ability of muscles to return to original length after stretching.

A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation.

• CHARACTERISTICS OF SOUND:
• a. Pitch or shrillness:
• b. Loudness and intensity:
• c. Quality or timbre:

Pure tones, harmonics, periodic and non-periodic sounds; Timbre, spectrum, envelope and transients.

Through this vibration, we hear the sensation of sound. Noises are categorized in four different ways. The things you hear throughout the day can be either a continuous noise, intermittent noise, impulsive noise, or low frequency noise.

• Pitch: The pitch is the characteristics of a musical sound which depends upon the frequency.
• Loudness: The loudness of musical sound is related to the intensity of the sound the higher is the intensity, the higher will be the loudness.
• Quality or timber: It measure the complexity of sound.

The fundamental building blocks of music are loudness, pitch, duration (or rhythm), tempo, timbre, and reverberation.

The two most important properties of sound are amplitude and frequency because amplitude determines the loudness of sound and frequency determines its pitch. The loudness and pitch affect the quality of sound.

Pure tones, harmonics, periodic and non-periodic sounds; Timbre, spectrum, envelope and transients.
