Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound:
loudness, pitch, and timbre
. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived.
What are the 5 aspects of sound?
They are the
frequency, amplitude, wave form and duration
, or in musical terms, pitch, dynamic, timbre (tone color), and duration. The frequency, or pitch, is the element of sound that we are best able to distinguish.
What are the 2 aspects of sound?
Sound is characterised by two aspects:
a physical and a sensory aspect
. In terms of physics sound is produced by a source that is caused to vibrate. This vibration results in variations in air pressure. The sound spreads through the air as waves.
What are the different aspects to sound?
Every sound has qualities. These qualities relate to different aspects of the sound, such as the volume or the duration. There are four sound qualities:
pitch, duration, intensity and timbre
.
What are 3 uses of sound?
- Sonar is used in navigation, forecasting weather, and for tracking aircraft, ships, submarines, and missiles.
- Sound finds many applications in entertainment electronics, radio, cassette, etc.
- Sound is very useful in communication.
What are the 5 uses of sound energy?
- Cellular Telephone.
- Motion Picture.
- Telephone.
- C.D.'s Televisions.
- Phonographs.
- Electronics.
- Hearing Aids.
- Video Tape Recorders.
How sound is useful in our daily life?
It
helps us to communicate with others
. By sound, we can understand the context of the words spoken. Sound can help people to protect themselves from danger such as the sound or horn of the train and other vehicles warn people to give way etc. … Without a sound, we would not be able to listen to music or watch movies.

What are two main properties of sound?
Properties of sound are
speed, loudness, and pitch
. Complete answer: Sound is a longitudinal wave which makes it possible for us to hear. Sound waves are usually considered as plane sinusoidal waves, which are specified by some certain properties such as frequency, amplitude, speed and direction.
What is this type of sound called?
There are two types of sound,
Audible
and Inaudible. Inaudible sounds are sounds that the human ear cannot detect. The human ear hears frequencies between 20 Hz and 20 KHz. Sounds that are below 20 Hz frequency are called Infrasonic Sounds.
What is the concept of sound?
Sound is a pressure wave which is
created by a vibrating object
. This vibrations set particles in the sur- rounding medium (typical air) in vibrational motion, thus transporting energy through the medium.
What is the sound of waves called?
In physics, sound is a vibration that propagates as an
acoustic wave
, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. … Sound waves below 20 Hz are known as infrasound.
Does sound travel up or down a hill?
In short,
Sound Travels in both directions up and down
, Sound is omnidirectional which means it can travel in any way and direction, however, there are some factors that may influence the direction of the sound.
What is the 4 uses of sound energy?
Ultrasound waves are
used to detect objects
. A ringing telephone, a honking horn, and the sound of a friend's voice are all reminders of how important sound is. But sound has uses that go beyond communication. For example, some animals and people use reflected ultrasound waves to detect objects.
How do humans use sound?
Sound travels through materials as a wave of pressure. … Although we cannot use sound energy to power our cars or light our homes, we can use sound energy to learn about our surroundings. The simplest and most obvious use of sound energy is for
hearing
. Humans can hear frequencies between about 20 Hz and 20,000 Hz.
