How does sound affect our daily lives?
Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is
Noise Induced Hearing Loss (NIHL)
. Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children.
What causes sound?
Sound is caused by
the simple but rapid mechanical vibrations of various elastic bodies
. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.
How do we produce sound?
How is Sound Produced? Sound is produced
when an object vibrates, creating a pressure wave
. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
What are the 3 application of sound?
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.
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 is sound used in medicine?
Sound waves
can assess potentially dangerous atherosclerotic plaques, monitor chronic liver disease
, and help deliver drugs to particular locations within the body. Ultrasound devices can image tumors deep inside the body, and acoustical energy can be focused upon those tumors as a way of treating cancer.
How does sound affect behavior?
Sounds affect our state of mind differently depending on whether they are pleasant or annoying. … People can
become finely attuned to the sounds that most disturb them
, heightening their annoyance. In the same way, an absence of pleasant sounds may also put us on high alert, because it offers no guarantees of safety.

tinnitus, hypertension, vasoconstriction
, and other cardiovascular adverse effects. Chronic noise exposure has been associated with sleep disturbances and increased incidence of diabetes.

Music is composed of
sounds with a fundamental frequency and overtones
. Noise is composed of sounds with frequencies that range continuously in value from as low as you can hear to as high as you can hear — not necessarily at equal intensity, however.
What are the 5 properties of sound?
Like any wave, a sound wave too has many characteristics. The five characteristics of sound are
amplitude, wavelength, period, frequency, and speed or velocity
.
What are the 4 properties of sound?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the
frequency, amplitude, wave form and duration
, or in musical terms, pitch, dynamic, timbre (tone color), and duration.
What is sound explain?
Sound is
a type of energy made by vibrations
. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.
