Measurements and Frequency Response in Headphones

WebThe most common weighting that is used in noise measurement is A-Weighting. Like the human ear, this effectively cuts off the lower and higher frequencies that the average person cannot hear. Defined in the sound level meter standards (IEC 60651, IEC 60804, IEC 61672, ANSI S1.4), a graph of the frequency response can be seen to the right. WebThe result was the HARMAN Target Curve, which when applied to headphones became the AKG Reference Response Acoustics Curve. As we mentioned above, the AKG K371 and K371-BT headphones are the first headphones to be engineered to match the AKG Reference Response Acoustics Curve. slaughterhouse tracklist

A-weighting is valid to represent the sensitivity of the human ear as a function of the frequency of pure tones. The A-weighting was based on the 40-phon Fletcher–Munson curves, which represented an early determination of the equal-loudness contour for human hearing. However, because decades of field experience have shown a very good correlation between the A scale and occupational deafness in the frequency range of human speech, this scale is employed in … WebFigure 5.18 Sounds in Everyday Life.
