acoustical correction
1Acoustical measurements and instrumentation — Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with …
2Digital room correction — An example of the frequency magnitude of a room response before and after digital room correction. Digital room correction (or DRC) is a process in the field of acoustics where digital filters designed to ameliorate unfavorable effects of a room… …
3Measurement microphone calibration — In order to take a scientific measurement with a microphone, its precise sensitivity must be known (in volts per Pascal). Since this may change over the lifetime of the device, it is necessary to regularly calibrate measurement microphones. This… …

6speech disorder — n. any conspicuous speech imperfection, or variation from accepted speech patterns, caused either by a physical defect in the speech organs or by a mental disorder, as aphasia, stuttering, etc. * * * ▪ medicine Introduction any of the… …
7Comparison of analog and digital recording — This article compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded using either digital or analog techniques. An analog… …
8Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… …
