Eardrum is a part of:
the sound producing organ of our body is larynx or the voice box and ear drum is not a part of it.We also know that ear drum is not a part of skeletal system skeletal system consists of bones and joints .We also know that eardrum is not a part of reproductive system. So show the option remains is the hearing organ and we know that the hearing organ of our body is ear and it has the eardrum which senses the vibrations and convert it into signals and transmit it to brain with the help of afferent nerves. So option "c"is the correct answer.
The hearing range of human ear is:
The voice box is also called:
Large amplitude of sound vibrations will produce:
The pitch of sound depends on:
Pitch is equal to frequency when there is no relative motion between the source and the listener.
Sound is a kind of
To and fro motion of an object is called
Voice box or larynx of human produces
Sound propagates maximum in
Sound propogates maximum in solid. The reason is that the particles are more closer to each other in a solid so transfer of sound energy is faster in solid than in liquid or gas.
Noise pollution is harmful for
Sound can travel in vacuum.
We can hear the sound of the frequency 20 Hz to 20,000 Hz.
Humans can generally sense sounds at frequencies between 20 and 20,000 cycles per second, or hertz (Hz)—although this range shrinks as a person ages. Prolonged exposure to loud noises within the audible range have long been known to cause hearing loss over time.
The sound cannot travel in solid materials.
The sound is caused due to propagation of vibrations.
The pitch of a sound depends on the frequency of the waves.
Ghatam is a musical instrument.
The correct option is A.
Ghatam, large, narrow-mouthed earthenware water pot used as a percussion instrument in India. Unlike other Indian percussion instruments, such as the tabla and mridangam, the ghatam does not have a membrane over its mouth.
Sound does not need a medium for propagation.
The number of oscillations per second is called amplitude.
The commonly used unit for the no. Of oscillations per second is the Hertz.
So, the given statement is false
The frequency determines the shrillness or pitch of a sound.
The shrillness of sound is pitch. The pitch of the sound depends on the frequency of vibrations. The higher the frequency, the more shrill is the sound.
The loudness is expressed in a unit called decibel.
The loudness of sound is measured in units called decibel (dB) . A decibel unit expresses the relative intensity if sounds on a scale from zero for the average least perceptible sound to about 100 dB, which is near the level most people find uncomfortably loud.
