Best answer: Where and how sound waves are transformed into electrical impulses?

SOUND WAVES enter the ear canal and cause the eardrum to vibrate. VIBRATIONS pass through 3 connected bones in the middle ear. This motion SETS FLUID MOVING in the inner ear. Moving fluid bends thousands of delicate hair-like cells which convert the vibrations into NERVE IMPULSES.

How are sounds detected?

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.

What turns vibrations into electrical signals?

The cells that line the inner ear and convert mechanical sound vibrations into electrical impulses are known as hair cells — named for the tuft of 30-300 cilia, or microscopic hairs, on each cell’s surface.

How are sound waves transmitted to the inner ear quizlet?

Your ear converts sound waves into nerve impulses that your brain interprets. … The ear canal is a hollow tube that carries the sound waves to the eardrum. The sound wave hits the eardrum, causing it to vibrate. The eardrum transmits these vibrations into the inner ear where they are amplified.

What is the pathway of sound vibrations to the inner ear quizlet?

Vibrations move via the oval window through the fluid in the cochlea (inner ear), which stimulates tiny hair cells. > Vibrations are transformed into electrical impulses that are perceived by the brain as sound. You just studied 15 terms!

What are the 5 characteristics of sound?

There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity.

Which sound is the softest?

The softest achievable phonatory sound level is an important characteristic of human voice.

ABSTRACT.

(1) Acquisition of Voice Handicap Index data.
(6) Recording of approximately 5 s of silence.
(7) Softest possible phonation, vowel [a:] at comfortable pitch.

How we are able to identify where a sound is coming from?

Humans use two important cues to help determine where a sound is coming from. These cues are: (1) which ear the sound hits first (known as interaural time differences), and (2) how loud the sound is when it reaches each ear (known as interaural intensity differences).
