![]() ![]() The human ear is more sensitive to certain frequencies than others, and a-weighting accounts for these differences by giving more weight to certain frequencies. The a-weighting was developed to better represent the sensitivity of human hearing. It is commonly used to measure the volume of ambient noise or music. dB(A): “dB(A)” stands for “decibel a-weighted” and refers to a type of sound level measurement used to indicate loudness in human hearing.It is also used to assess the quality of audio recording and playback devices and to ensure that the audio signal is not distorted during playback. The term dB FS is often used in relation to digital audio signals to indicate how loud or quiet the signal is compared to its maximum amplitude. A signal with a value of 0 dB FS thus has the maximum amplitude possible, while a signal with a value of -6 dB FS has half the maximum amplitude. When a signal is specified in dB FS, the amplitude of the signal is expressed in terms of that maximum amplitude. The term full scale (FS) refers to the maximum amplitude that a digital audio signal can have. It refers to the possible dynamic range of a digital audio signal encoded in a particular format. dB FS:”dB FS” stands for “decibels relative to full scale” and is often used in relation to digital audio signals.It is often used to indicate the loudness of music or sounds that are audible to the human ear. Phon: A unit used to measure the intensity of sound in human hearing.Neper: A unit used to measure gains in electromagnetic fields and optics.1 Bel corresponds to an amplification of 10 dB. Bel: A unit used to measure the gain of electrical signals.There are also other units used for more specific applications.
