How can we produce sound?

The vocal folds (vocal cords) are attached within the larynx to the largest of the laryngeal cartilages known as the thyroid cartilage or “Adam’s apple”. The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs.

How is sound produced Class 7?

Sound is produced by vibration. When a body vibrates, it forces the neighbouring particles of the medium to vibrate. This creates a disturbance in the medium, which travels in the form of waves. This disturbance, when reaches the ear, produces sound.

How is sound produced Class 10?

For example – A speaker produces sound by using electrical energy to make the diaphragm installed on the speaker to vibrate. These vibrations are passed on to the air molecules or the molecules by which the medium is made of.

How is sound produced 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.

How is sound produced by Brainly?

The production of sound is a process that is carried out by vibrating objects. Any object upon vibration produces sound waves which are then accepted by the human ear. The vibrated objects expose a longitudinal wave which can also termed as sound wave.

What objects can produce sound?

Any object that vibrates will create a sound. The sound could be musical or it could be noisy; but regardless of its quality, the sound wave is created by a vibrating object. Nearly all objects, when hit or struck or plucked or strummed or somehow disturbed, will vibrate.

What are types of sound?

  • 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. …
  • Sounds that are above 20 KHz frequency are called Ultrasonic Sounds.

What is sound 8th class?

Sound is a form of energy and it comes from vibrations. These vibrations create sound waves which move through mediums such as air and water before reaching our ears. Understand how sound waves come from vibrations in the form of compression and rarefaction and how your ears give you the ability to hear them.

What is amplitude class 8?

The maximum displacement of a vibrating object from its Central position is called the amplitude of vibration. The amplitude actually tell us how far the vibrating object is displaced from its central position.

How is Class 8 Brainly produced?

Answer: A sound is produced by a vibrating body. … When a body vibrates, it produces sound in the surrounding medium. The vibrations are transferred to the medium surrounding the sound source.

How is sound produced answer the following question?

The back and forth movement of an object produce sound. An object moving back and forth is said to be in vibration. Hence, the sound is produced by vibrating objects.

How is sound produced in a human larynx and a loudspeaker?

Two vocal cords are stretched throughout the voice box in such a way that it leaves a narrow slit between them for the passages of air. When lungs force air by the slit, the vocal cords start vibrate and produce sound. At the upper part of a loudspeaker, there is a metal cone.

How does sound travels Brainly?

Answer: Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate.

How does sound move in solids liquids and gases?

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.

How does a drum produce sound?

Striking the head of the drum changes its shape and compresses the air inside the shell. The compressed air presses on the bottom head and changes its shape. Then, these changes are transmitted to the drum shell and reflected back, and this action is repeated, creating a vibration.

How sound is produced in an electric bell?

An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound.

How do bells hear sounds?

When a bell is struck, the metal vibrates. The vibrations travel through the air as sound waves. When these waves reach our ears, they make our eardrums vibrate, and we hear the sound of the bell ringing.

What is sound short answer?

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 sound example?

Sound is vibration in air and water that stimulate the nerves inside the ears to create the sensation of hearing. An example of sound is music. An example of sound is voices. Sound is defined as to have a particular tone or seem a certain way.

What are 3 types of sound?

  • Sonic: It is a sound with the frequency between 20 to 20,000Hz. …
  • Ultrasonic: It is a sound with a frequency more than 20,000Hz.

What are examples of natural sounds?

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 a wave sound?

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person’s vocal chords.

How is sound propagated?

Sound propagates through air or other mediums as a longitudinal wave, in which the mechanical vibration constituting the wave occurs along the direction of propagation of the wave.

Do all bodies produce sound?

How sound is produced in a speaker?

The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.

How is sound produced in a human larynx answer?

The larynx is involved in swallowing, breathing, and voice production. Sound is produced when the air which passes through the vocal cords causes them to vibrate and create sound waves in the pharynx, nose and mouth. The pitch of sound is determined by the amount of tension on the vocal folds.

How is a sound produced in a loudspeaker?

The part of the speaker that converts electrical into mechanical energy is frequently called the motor, or voice coil. The motor vibrates a diaphragm that in turn vibrates the air in immediate contact with it, producing a sound wave corresponding to the pattern of the original speech or music signal.

When you clapped your hands slowly and lightly what kind of sound did you produce?

When you clap your hands, you displace (or move) the air particles between and around your hands. This creates a compression wave that travels through the air (much like it did in the water). A continuous sound (such as the one produced by a tuning fork) is caused by the vibrations of the fork tines.
