How do animal detect sound?

Answer 1

Animals that have ears detect sound using their ears, just like people do. Other animals use echo location and vibration to detect sounds, which can often help them avoid a predator or find food.

Answer 2

Animals detect sound through structures in their ears, such as the eardrum and inner ear. Sound waves enter the ear canal and cause vibrations in the eardrum, which are then converted into electrical signals that the brain interprets as sound. Different animals have adaptations that help them detect and interpret sounds specific to their environment and survival needs.

Answer 3

The body detects sounds by converting sound/air motion to electrical energy. A membrane between the outer world and the inner ear transfers it's energy to several bones (malleus, incus and stapes) which then moves the fenestra ovalis which moves another membrane passing it's energy to the cochlea and there is converted to fluid movement then electrical changes in neurons. These changes are passed to the brain as sensations. A microphone does a similar job - it converts sound to changes in electrical energy.

Answer 4

Any transducer that converts sound into an electrical signal will do this.

An electromagnetic microphone, a condenser microphone; or your ears convert the pressure waves of sound into electrical signal in the Auditory nerve.

Answer 5

The human ear consists of three parts, the outer ear that consists mainly of the ear lobe. The middle ear lies next. It consists of the ear drum and three bones. The inner ear is comprised of the oval windows, the auditory nerve, the cochlea tube and the semi-circular canals.

The ear lobe receives incoming sound waves and directs them along the canal (about 3cm) towards the ear drum, called the tympanic membrane. The compressions and rarefactions of the longitudinal sound waves cause the ear drum to vibrate. These vibrations are picked up by three bones in the middle ear. These bones act as a lever system for force and pressure amplifications of about 25 times at the oval window.

Vibrations at the oval window cause pressure waves to be formed in the fluid of the inner ear housing the cochlea tube. Inside the cochlea tube, the pressure waves are picked up by the sensory cells that in turn produce neural impulses that are carried by the auditory nerves to the brain. Hence sound is heard.

Answer 6

The ear :)

Sound waves travel through your external auditory tube and into the auditory canal. The vibrations hit your tympanic membrane which moves your ear ossicles (bones - the malleus, then the Incus, then the Stapes) which in turn send the vibrations to the cochlea. The cochlea contains hairlike structures which move differently according to the different vibrations and send this information to your brain through the auditory nerve.

Answer 7

Your eardrum has a membrane that is sensitive to these vibrations and these nerves fire when the vibration a sensed sending a signal of sound to your brain.

Answer 8

Sound waves are produced by vibrating matter (water, air,etc). Sound is detected by by those vibrations coming into contact with a membrane such as an eardrum.

Answer 9

With microphones.

Answer 10
