The journal is devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. According to the Journal Citation Reports, the journal has a 2022 impact factor of 4.7. [1]
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...
In the case of a homogeneous, isotropic system, the quality is proportional to the FWHM. This sense of the phrase is the precursor of the usage of the word in music theory. In music theory, quality is the number of harmonics of a fundamental frequency of an instrument (the higher the quality, the richer the sound).
The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years.

The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.
A damping factor of 20 or greater is considered adequate for live sound reinforcement systems, as the SPL of inertia-related driver movement is 26 dB less than signal level and won't be heard. [7] Negative feedback in an amplifier lowers its effective output impedance and thus increases its damping factor.
The former title of this journal was American Physics Teacher (vol. 1, February 1933) (ISSN 0096-0322).It was a quarterly journal from 1933 to 1936, and then a bimonthly from 1937 to 1939.
SNR is an important parameter that affects the performance and quality of systems that process or transmit signals, such as communication systems, audio systems, radar systems, imaging systems, and data acquisition systems. A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is ...
