What is necessary for production of sound?
Sound is the result of three things. First, something must vibrate. A tree hitting the ground also causes a lot of vibrations. Second, you need something through which the vibrations (sound waves) can travel.
What are the conditions necessary for transmission of sound?
Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.
What are two necessary conditions for the production of sound?
Originally Answered: What are the necessary conditions for sound to be produced? You need two, maybe three things – something that’s vibrating, a medium for those vibrations to propagate in, and a listener to hear it (or recording equipment to pick it up).
What is necessary for production of sound write answer in one sentence?
Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air, etc.) around it to vibrate thus producing sound.
What are the three requirements of sound?
Three components are needed for sound to be heard:
- A source – where the sound is made.
- A medium – something for the sound to travel through.
- A receiver – something to detect the sound.
Can sound waves travel in vacuum?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
What is sound and its properties?
Sound is the transfer of energy from a vibrating object in waves that travel through matter. Properties of sound include speed, loudness, and pitch. The speed of sound varies in different media. The loudness of sound depends on the intensity of sound waves. The pitch of sound depends on the frequency of sound waves.

What is sound and its types?
Sound can be of different types—soft, loud, pleasant, unpleasant, musical, audible (can be heard), inaudible (cannot be heard), etc. For instance, the sound produced when an aeroplane takes off is both loud and unpleasant.
What are the two types of sound?
Sound has two basic forms: acoustic energy and mechanical energy. Each type of sound has to be tackled in their own way. Acoustic energy or sound is what we experience every day. It is in fact vibration of air (sound waves) which is transformed by the tympanic membrane in the ear of human to audible sounds.
What are the sources of sound?
Sound can travel through wood, steel, water, and countless other materials. Sound sources can be divided into two types: natural and artificial, or human-made. Examples of natural sources are animals, wind, flowing streams, avalanches and volcanoes.
What is the difference between soft and loud sound?
Loud and soft sounds have a few differences. One is that a loud sound has more energy then a soft sound. Another difference is that a soft sound has less decibels then a loud sound. The more a surface vibrates the louder the sound is.
What is a high sound?
A high- frequency sound is about 2,000 Hz and higher. Intensity is measured in decibels (dB) [DES-uh-buls]. A high-intensity (loud) sound has a high decibel level. A low-intensity (soft) sound has a low decibel level. The sound of people talking is usually between 40 and 60 dB.
What are the loudest sounds?
‘What?! I can’t hear you! ‘ The loudest sounds ever recorded
- Krakatoa eruption of 1883 (310dB)
- Tsar Bomba (224dB)
- Saturn V Rocket (204dB)
- Chelyabinsk meteor (180dB)
- Howler monkeys (140dB)
- Republic XF-84H ‘Thunderscreech’ (est 200dB)
- Large European Acoustic Facility (LEAF) (154dB)
What frequency can kill you?
The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
What are the top 10 loudest sounds?
Know your decibels! Ten of the loudest sounds out there
- 230 dB – Sperm whale.
- 180 dB – Rocket launch.
- 120 dB – Fireworks.
- 110 dB – Live gig.
- 100 dB – Night club.
- 97 dB – Fire alarm.
- 94 dB – Lawnmower.
- 88 dB – Heavy traffic.
How many decibels can kill you?
150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB.
What Hz is harmful?
Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity.
How loud can a human yell?
Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears!
Can 200 decibels kill a human?
Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
What is the loudest sound in the universe?
The 1883 Krakatoa volcano eruption was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can’t hear them.
