What else can I help you with?
What is the external feature of ear that contains the helix and lobule?
The external feature of the ear that contains the helix and lobule is the pinna, also known as the auricle. The pinna is the visible part of the ear that collects sound waves and directs them into the ear canal.
Which form of energy is used to produce sound?
Sound energy is produced by vibrating objects, which convert mechanical energy into sound waves. The sound waves travel through a medium, such as air or water, to reach our ears and be perceived as sound.
Which part of the ear changes sound energy into electrical energy?
The cochlea is the part of the ear that changes sound energy into electrical energy. It contains hair cells that are responsible for converting the mechanical vibrations of sound waves into electrical signals that can be interpreted by the brain.
Is electrical energy changed to sound energy in a radio speaker?
Yes, electrical energy is converted into sound energy in a radio speaker. The electrical signals from the radio receiver are sent to the speaker, which contains a magnet and coil that vibrate to produce sound waves.
What is the name of the device which converts electrical energy into sound energy?
Speaker (!?) Plus, I would use the phrase sound waves instead of sound energy.
What contains sound energy?
As you may know, the sound energy is basically a wave or many waves traveling through the air( or anything that is not a void ) and those waves carry energy not matter. the sound waves or sound energy is a part of kinetic energy because the energy is not waiting to be unleashed, in fact it's moving within the air or any other material
What is shock waves in fluid mechanics?
The speed of sound is constant in solids, liquids and gases. If something happens in such a medium the mechanical energy of it can propagate only at the speed of sound. If something is traveling through the medium faster than the speed of sound then it is pumping energy into a wave that contains more energy than what the simple passage of the object contains. This is the sonic boom hear by passing jet aircraft.
What energy is in a firecraker?
A firecracker contains chemical energy stored in its gunpowder or explosive material. When ignited, the chemical reactions release this energy in the form of heat, light, sound, and pressure.
Which feature of the ear is most medial?
The cochlea is the most medial feature of the ear. It is a spiral-shaped structure responsible for hearing and contains the sensory cells that convert sound waves into electrical signals sent to the brain.
Which part of the ear changes sound energy in to another form of energy?
The cochlea is the part of the ear that changes sound energy into electrical signals that can be interpreted by the brain. It contains hair cells that vibrate in response to sound waves, converting them into neural signals that are sent to the brain via the auditory nerve.
Which part of the ear contains tiny hairs that bend and twist after receiving sound vibrations?
The cochlea, a part of the inner ear, contains tiny hair cells that bend and twist in response to sound vibrations. These hair cells convert the mechanical energy of sound waves into electrical signals that can be interpreted by the brain as sound.
What wave contains compressions and rarefractions?
A sound wave contains compressions (areas of high pressure) and rarefactions (areas of low pressure). These variations in pressure create the wave pattern that carries sound energy through a medium, such as air or water.
