Noise reduction enhances voice communications by reducing background noise to effectively increase the SNR of speech

VOCAL’s Noise Reduction solutions are used in military, industrial and commercial applications such as cockpits, call centers, and other challenging acoustic environments that can interfere with effective voice communications. Our Microphone Noise Reduction solutions provide different methods to enhance speech depending on the system configuration and information available.

Our experience in the development and configuration of mobile, network, and telephony applications will help you select the right noise solution for your product design. Contact us to discuss your noise reduction requirements.
