What would happen to the loudness of sound with increase in its frequency?

The "loudness" of a sound is measured in decibels. Every time the number of decibels is increased by ten the amount of energy the sound waves carry doubles and therefore seems twice as loud. The "loudness" of a sound is not effected by the frequency, but by the decibels. However, some frequencies (mostly at the very limits of human hearing) will seam quieter. Also many bass frequencies seem louder because (of the audible spectrum of sound) they carry the energy the most efficiently through the air around us.
A2 The loudness of a sound is a subjective phenomenon - to a human, we have a poor sensitivity to low frequemcy sounds, rising in the range of a few kilohertz, and again declining at frequencies much over 15 kilohertz. Additionally, the advertising industry for example takes advantage of the fact that we consider an advert louder if the signal is adjusted such that the sound spends much of its time at a higher level, but without the peak signals being exceded. This is done by a sophisticated form of signal clipping.
And in the audio equipment industry, 'music power' is often quoted as the equipments output, rather than the more academic 'RMS' (Root Mean Square) of the signal.
So, loudness is a subjective idea.

What part of a sound is decided by the frequency of its vibrations?
The frequency of a sound determines its pitch. Most sounds are composed of many frequencies. The other major component of sound is its amplitude, or its loudness.
Which characteristic of sound is associated with frequency?
We perceive the loudness of a sound wave as a consequence of its amplitude. The frequency of a sound wave determines the pitch we perceive.
What is a property of sound that changes with frequency?
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
The pitch of a sound is determined by its and speed together or its frequency alone?
The pitch of a sound can be determined by its frequency alone.
The frequency of a sound wave determines what?
The rate at which the sound source is vibrating :) --> novanet answer
Pitch is to frequency as loudness is to?
Loudness depends on the amplitude. square of amplitude is proportional to the loudness. Pitch is decided by the frequency. One can sing at higher pitch but at lower voice.
Pitch describes the loudness of a sound?
Pitch describes the frequency of a sound.
Pitch is to frequency of sound as loudness is to?
Amplitude/Intensity
How does amplitude affect the loudness of vibration?
Generally speaking, we perceive an increase in amplitude as an increase in loudness. However, at the higher end of the scale of Sound Pressure Level we are less sensitive to incremental changes. The loudness we experience also varies with frequency. For instance, we are not as sensitive to soft sounds when they are in the low frequency range (20Hz - 700Hz).Loudness is partly a function of the way in which our ears physically respond to sound. However, the brain/mind plays a big part in how loudness is perceived. Loudness is a characteristic of sound that is primarily a psychological correlate of its physical strength. We can conceive of the (objective) physicalstrength of sound as its amplitude. Then, as we might imagine, the overall effect is that loudness increases with amplitude.
Which is a similarity between loudness and pitch?
There is no similarity. Loudness has to do with sound pressure amplitude coming from the sound source. Pitch has to do with the frequency of the tone the sound source is making. Loudness cannot be pitch.
What is pitch and loudness and timbre?
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
Does a sound's pitch depend on its loudness?
No. A sound's pitch depends on the frequency of the wave.
When the loudness of a sound and amplitude of a sound increases the amplitude of the sound produced will be?
The loudness of a sound is the same thing as the overall amplitude of a sound. When measuring sound, in general, you have pitch (frequency) and tone (amplitude, the measure of loudness). So, if you increase the amplitude of a sound wave pattern, you increase the overall intensity of the sound (the energy), and that can be measured on the logarithmic scale of decibels, since an unconstrained, undirected sound wave carries its energy outward in all directions, in an increasing volume of air (or other medium).
What does loudness increase with?
Loudness increases with increasing amplitude of the sound wave, also called increasing sound pressure.
Which of these is associated with a sound's loudness?
Loudness is affected by parameters other than sound pressure, including frequency and duration. also sound wave amplitude
Does frequency measure loudness?
sort of but the main measurement for sound is decibels
What depends on the loudness of sound of a sound wave?
The 'Loudness' of a sound wave is dependent on its Amplitude, hence why we have 'amplifiers' to increase the volume of something.
