DSP is often confused with actual digital systems. These two terms both allude to different concepts. Digital signal processing is slightly more abstract in nature than actual digital systems. A digital system is a hardware, binary code, or digital domain involved. The general confusion between these two terms may be because they are both so intertwined. DSP can be done on just about any digital platform out there, but some systems are specifically designed for DSP.
Digital signal processing, which is the focus here, can be defined quite simply as the processing of a signal in the digital domain to analyze, measure, and manipulate said signal using mathematical calculations. Digital signal processing involves the interchanging of information so that said information can be observed, analyzed, or transformed into a separate form of signal. As you can imagine, this takes place very quickly - the entire process is not even noticed by the user. However, digital signal processing is a critical element of a good headset.
There are a handful of different “parts” that make up a successful DSP system:
Digital signal processing is important because it significantly increases the overall value of hearing protection. Unlike passive protection, DSP suppresses noise without blocking the speech signal. Obviously, this is a very important aspect of protecting user hearing, especially when users are immersed in industrial work environments. DSP systems protect users from unhealthy noise exposure without compromising communication. Here are a few more reasons why DSP is valuable:
Digital signal processing is used everywhere. DSP is used primarily in areas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals. For example, digital signal processing is used for speech compression for mobile phones, as well as speech transmission for mobile phones. DSP is also used in elite headset equipment to protect users from hearing damage; the same suppression and enhancement concept is equally important here. Leading industries in the field of hearing protection and on-the-job communication such as Sensear use digital signal processing to create a safe, quality communication experience. Other applications include mp3 file manipulation, CAT scans, computer graphics, MRI, and even amplifiers for certain electric guitars.
The purpose of digital signal processing is, as mentioned before, to filter analog signals from current time and space. It is used in a wide variety of technological equipment but is an especially critical aspect of noise suppression and voice enhancement communication equipment.
