Do all bodies produce sound?
All the bodies with air flow or any other medium can produce sound. The body with vaccum in it cannot produce any sound. Sound easily passes in the air medium, the wave formation decides the pitch and freqency. The sound can also travel in water bodies.
Do all vibrating bodies produce sound Class 8?
CBSE NCERT Notes Class 8 Physics Sound. Sound is produced by a vibrating body. In other words, any vibrating body would always produce sound.
Do humans vibrate at different frequencies?
The important parts of the human body vibration frequency are generally located in about 3 Hz–17 Hz. According to the International Standard ISO 2631 in the vertical vibration of the human body, the sensitive range is located in 6 Hz–8 Hz. ... The natural frequencies of the head and spine are closer to them.
Is sound real?
Sound is pressure waves through matter. If there's no matter, there's no sound. ... It makes an air pressure wave and that's it. The concept of sound is by definition a biological being's perception of the pressure wave—and if there are no ears around to perceive the pressure wave, there's no sound.
Does a vibrating body always produces sound?
No. Sound is produced only when frequency of vibrating lies between 20Hz and 20kHz.
Do all animals produce sound by vocal cords?
Answer : No all animals do not produce sound by vocal cords.
Do vibrating bodies produce sound?
When a body vibrates, the vibrations in the body also start vibrating the particles in the surrounding medium. These vibrations are transferred through the medium in which the body is vibrating. ... This proves that the vibrations in a body produce sound.
Do all vibrating bodies produce same sound Explain with examples?
yup.....but the vibration must be rapid ,,,only they it can produce sound. for explain.... playing drum or even when you talk ( the vocal chords or the larynx vibrate by quickly opening and closing the bar.....
Is it true that vibrating bodies do not produce sound?
- No. Vibrating bodies do not produce Sound. All vibrating bodies produce vibration in the molecules of the medium they are (for example air).
Is it normal for a dead body to make noise?
- Yes they do, normally due to breakdown of the tissues which produces gas, so prior to embalming it is fairly normal to make odd sounds and sometimes even movement. As a point of interest even when a person is dead their hair, beard and nails continue to grow for a few days.
How does sound work in the human body?
- Sound works in a similar way, just the source is much bigger and when the vibrations reach our ears, they make our eardrums vibrate too. Eardrums have a connection with the brain. And this is how the eardrums tell our brain the vibration pattern and our brain tells us what sound is that.
How are music and sound used in everyday life?
- Music and sound are part of our everyday life. A sound is a form of energy that gives us hearing experience. We see objects around us with the help of eyes by detecting light from objects. In the same way, ears are used to detect sound.
