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 else can I help you with?
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 pitch in sounds?
In sound, pitch refers to how high or low a tone is perceived. It is determined by the frequency of the sound wave, with higher frequencies corresponding to higher pitches and lower frequencies to lower pitches.
The human perception of sound intensity is called?
The human perception of sound intensity is called loudness. Loudness is influenced by the amplitude or energy of the sound wave and is measured in decibels (dB).
What is the pitch of a sound is most closely related to?
The pitch of a sound is most closely related to the frequency of the sound wave. Higher frequency sound waves are perceived as higher pitch, while lower frequency sound waves are perceived as lower pitch.
Does loudness of sound increase with frequency?
No, the loudness of a sound is related to its intensity, which is determined by the energy of the sound wave. Frequency refers to the number of vibrations per second and is perceived as pitch. In general, higher frequency sounds are perceived as more "sharp" or "high-pitched," but this does not necessarily mean they are louder.
Is the frequency determined by it loudness or not?
No, the frequency of a sound wave is determined by its pitch, while the loudness is determined by the amplitude of the wave. Frequency refers to how high or low a sound is perceived, while loudness refers to the intensity or volume of the sound.
Does frequency measure loudness?
No, frequency measures the pitch of a sound, not its loudness. Loudness is typically measured in decibels, which represent the intensity or volume of a sound. The higher the decibel level, the louder the sound.
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.
How do you compare loudness and pitch o a sound?
Loudness refers to the intensity or volume of a sound, while pitch refers to the frequency of the sound waves. A loud sound has higher amplitude and is perceived as stronger, whereas pitch is determined by the frequency of sound waves and how high or low they are. In summary, loudness is about the strength of a sound, while pitch is about its frequency.
If a sound gets louder does the wavelength of the sound it produces increase?
No, the wavelength of a sound does not change when the intensity or loudness of the sound increases. The wavelength of a sound wave depends on the frequency of the sound, which is determined by the source of the sound.
Pitch is to frequency of sound as loudness is to?
Amplitude/Intensity
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.
Does a sound's pitch depend on its loudness?
No. A sound's pitch depends on the frequency of the wave.
Is it true that a sound with a higher frequency is louder than one with a lower frequency?
No, frequency and loudness are two separate properties of sound. Frequency refers to how many cycles of a wave occur in a second, while loudness refers to the magnitude or intensity of a sound. A sound with a higher intensity is perceived as louder, regardless of its frequency.
Pitch describes the loudness of a sound?
Pitch describes the frequency of a sound.
When a source of sound approaches you what do you detect an increase in?
When a source of sound approaches you, you detect an increase in the loudness or volume of the sound. This is due to the compression of sound waves as the source moves closer to you, causing the waves to reach your ears more frequently.
