Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived.
Q. What triggers a neural signal in the ear?
As the hair cells move up and down, their bristly structures bump up against an overlying membrane and tilt to one side. This tilting action causes pore-like channels, which are on the surface of the bristles, to open up. When that happens, certain chemicals rush in, creating an electrical signal.

Q. What are the 4 tasks of the auditory system?
What are the four tasks of the auditory system? – Pick up stimulus energy from the world around us. – Change that energy into a pattern of neural impulses. – Carry those impulses to the proper locations in the brain.
Q. What does the auditory system do?
The auditory system is a body system that is responsible for the sense of hearing. It is divided into two subsystems- the peripheral auditory system (outer ear, middle ear and inner ear) and the central auditory system (from the cochlear nucleus up to the primary auditory cortex).
Q. How is loudness of sound determined?
The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). Intensity of sound results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.
Q. What is the loudness of sound called?
The loudness of a sound is called. the sound wave. the volume.
Q. How is loudness related to frequency?
Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in decibels (dB).
Q. How is loudness affected by frequency?
The pitch of a sound is dictated by the frequency of the sound wave, while the loudness is dictated by the amplitude. When a drum is beaten, the air particles around the drum skin vibrate in the form of a compression wave.
Q. Does loudness depend on intensity?
Loudness is not only the energy of sound that is reaching till the human ear but it also depends on detection of sound waves by our human ear. Loudness relies upon intensity of sound and intensity of sound is the amplitude of sound waves. Loudness of sound also depends upon the sensitivity of sound.
Q. Can loud noises kill you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.
Q. Can Bass kill you?
A coroner recorded a verdict of natural causes, saying the straight-As student was killed by sudden arrhythmic death syndrome (SADS), a heart disorder which kills 12 young people a week. …
