As a theoretical model, it helps to elucidate many of the properties of a sound wave. Wavelength, period, and frequency Figure 1C is another representation of the sound wave illustrated in Figure 1B. As represented by the sinusoidal curve, the pressure variation in a sound wave repeats itself in space over a specific distance.

Sound is perceived in three dimensional space based on the time difference it reaches our left and right eardrums. These six properties of sound are studied in the fields of music, physics, acoustics, digital signal processing (DSP), computer science, electrical engineering, psychology, and biology.

The basic properties of sound are: pitch, loudness and tone. Figure 10.2: Pitch and loudness of sound. Sound B has a lower pitch (lower frequency) than Sound A and is softer (smaller amplitude) than Sound C. Pitch. The frequency of a sound wave is what your ear understands as pitch.

In this section we will be looking at the basic properties of sound. Sound is a longitudinalwave. Remember that longitudinal waves are made up of areas where the wave is compressed together, and other areas where it is expanded. This would agree with the way that humans themselves make sounds.

The speed of sound is how fast the wave or vibrations pass through the medium or matter. The type of matter has a large impact on the speed at which the sound will travel. For example, sound travels faster in water than air. Sound travels even faster in steel.

The minimum distance in which a sound wave repeats itself is called its wavelength. That is it is the length of one complete wave. It is denoted by a Greek letter λ (lambda). We know that in a...

Sound travels in the form of a wave. Waves are characterized by three basic quantities. They are frequency, speed, and amplitude. Two of the main characteristics of sound are pitch and loudness, which in turn are determined by the frequency and amplitude of the wave, respectively.

Loudness is the strength of sensation of sound perceived by the individual. It is measured in terms of decibels. Just audible sound is about 10 dB, a whisper about 20 dB, library place, 30 dB, and normal conversation 35-60 dB, heavy- street traffic 60-80 B. sounds beyond 80 bB can be safely regarded as pollutant as it harms hearing system.
