What are the possible applications of equal-loudness contours?

What are the possible applications of equal-loudness contours?

Equal-loudness-level contours provide the foundation for theoretical and practical analyses of intensity-frequency characteristics of auditory systems. Since 1956 equal-loudness-level contours based on the free-field measurements of Robinson and Dadson [Br.

What is the equal loudness curve What are other names for it what does it state and why is it important to us?

Fletcher and Munson are credited with pioneering work in the 1930s to develop equal-loudness curves, contributing significantly to the understanding of the loudness response of the human ear. Sets of equal-loudness contours are still often referred to as Fletcher-Munson curves.

What are equal loudness curves quizlet?

Terms in this set (28) equal loudness contour. a curve showing the amplitude of tones at different frequencies that sound about equally loud. measure of sound pressure.

What does the equal loudness plot represent?

Equal-loudness contour is a measure of sound pressure over a spectrum of frequencies that are perceived as being equally loud to the hearer when expressed as a pure, constant tone. The measurement for loudness is the ‘phon’ and this is determined by referencing equal loudness contours.

What does the equal loudness curve demonstrate?

Equal loudness curves indicate that our perception of frequencies changes based on playback volume, at least for pure-tones. Doing so will help to ensure that your judgement is not thrown off by the effects that playback level can have on your perception of different frequencies.

What is the practical implication of equal loudness contour?

The concept of equal loudness contours is applied to hearing conservation measures. The ear is more sensitive to high frequency sound waves than it is to lower frequency sound waves, thus the actual effect on the human ear in terms of pressure exerted by sounds is taken into account.

At what frequency are we the most sensitive on the equal loudness contour map?

The solid lines are the equal-loudness contours for 10–90 phons as specified by the ISO 226 standard. Additionally, the corresponding sone values are given. The dashed line is the threshold of hearing. We are most sensitive to frequencies around 2 and 5 kHz.

What do you understand by equal loudness curve or phone?

What do equal loudness curves show?

What does the equal loudness principle tell us about how we perceive different frequencies?

Equal loudness curves indicate that our perception of frequencies changes based on playback volume, at least for pure-tones. How this translates to real-world sounds and music is not entirely understood. Nonetheless, this points to the importance of mixing and mastering at calibrated volume levels.

What does equal loudness contour represent?

How are equal loudness contours related to frequency?

ISO equal-loudness contours with frequency in Hz. An equal-loudness contour is a measure of sound pressure ( dB SPL ), over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones.

How is the Equal loudness contour related to SPL?

Equal-loudness contour. An equal-loudness contour is a measure of sound pressure ( dB SPL ), over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon, and is arrived at by reference to equal-loudness contours.

What do you call a set of equal loudness curves?

Sets of equal-loudness contours are still often referred to as Fletcher-Munson curves. The above curves follow the equal-loudness curves resulting from the measurements of Robinson and Dadson in the mid 1950s and are adapted from the depiction of the curves in Donald Hall’s book “Musical Acoustics”.

When did Fletcher and Munson develop the Equal loudness curve?

Fletcher and Munson are credited with pioneering work in the 1930s to develop equal-loudness curves, contributing significantly to the understanding of the loudness response of the human ear. Sets of equal-loudness contours are still often referred to as Fletcher-Munson curves.
