The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations. Better control the sound pressure level SPL.

∙ 14y agoIntensity of sound (mechanical) wave is directly proportional to the square of the amplitude of the wave. Hence by increasing the amplitude of vibration of the source of sound namely the throat membrane the intensity could be increased. Then we say it as louder.

∙ 14y agoBased on the equation velocity = wavelength * frequency, frequency is dependent on both wavelength and the velocity of the wave. Also, frequency is also directly related to the pitch of a sound.

Which two properties of a sound wave change when a sound gets louder?
It was when the air hit the wave and it move to another direction
What are the characteristics of sound waves?
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.
What gives a sound wave its pitch and intensity?
A sound wave's pitch is determined by its frequency; that is its cycles per unit of time. The sound wave's intensity or volume is determined by its amplitude; the maximum crest of a sound wave.
What if the molecules from a sound wave are compressed?
Nothing. That IS how a sound wave is propagated.
Is a sound wave continuous?
A sound wave is continuous for as long as the sound vibrations are being made at its source.
What is the Doppler efect?
A change of frequence in a wave (usually in a sound, or electromagnetic wave), due to the relative movement between the source of the sound and an observer.A change of frequence in a wave (usually in a sound, or electromagnetic wave), due to the relative movement between the source of the sound and an observer.A change of frequence in a wave (usually in a sound, or electromagnetic wave), due to the relative movement between the source of the sound and an observer.A change of frequence in a wave (usually in a sound, or electromagnetic wave), due to the relative movement between the source of the sound and an observer.
Which two properties of a sound wave change when a sound wave gets higher?
Its wavelength increases and its frequency decreases
The change in frequency of sound waves in the Doppler effect is heard as a change in?
Whenever the frequency of a sound wave changes, regardless of what caused it to change, the change is perceived as a change in the pitch of the sound.
Which relation is there between wavelength and height?
There is no relation between wave length and wave height. You can change the wave height independently from the wave length. Wave height tells you which amplitude the wave has. If you think of sound that means how loud it is. The wave length tells you the pitch or the frequency of this sound, that means high or low sound. Long wavelength means bass sound and short wavelength means treble sound.
A change in frequency is a change in what?
A change in frequency is a change in pitch, in terms of sound. try to picture a sine wave in your mind. When you lower the frequency of the wave, it stretches the sine wave out (Which is how the pitch of the sound is lowered. I'm assume that you're question is about Audio.) For example, if you had a sound wave at 440Hz (And is aslo the musical note "A" on the center octave), and you changed its frequency to 329.63Hz, it would then sound lower in pitch (The musical note of "E") I hope that helps ;) ~Mitch
Does the wave speed change in the Doppler effect?
Yes, the Doppler effect defines the change in speed of a sound wave due to motion. As I recall, the Doppler Effect is a change in the frequency of a wave, not its speed. Yep, I'm pretty sure Doppler is a frequency change, not a speed of sound change.
Is a sound wave a transverse wave?
No, a sound wave is a compressional wave.
Which property of the sound wave undergoes a change with an increase in its energy?
b
Why do particles in a substance not change position after a sound wave has passed?
proton
Which two properties of a sound wave change when a sound gets louder?
It was when the air hit the wave and it move to another direction
Is a sound wave a electromaginic wave?
No. A sound wave is a pressure wave.
Is a EM wave a sound wave?
electromagnetic wave is not a sound wave
