Aimed at a number of different radio related and voice communication markets, the products all incorporate unique Digital Signal Processing (DSP) technology to enable clear communications in noisy environments.
Founded in 2002, bhi quickly came to market with their first noise cancellation product, the NES10-2 DSP noise-eliminating speaker. Other products soon followed as bhi rapidly established a worldwide distribution network for their products in over 17 countries. They now have a comprehensive range of DSP noise elimination products and accessories for a wide range of applications and markets.

Our Markets
It can be very difficult to understand what is being said when calling or communicating from a noisy environment. bhi’s noise cancellation products will integrate into most voice communication systems to greatly reduce this inherent problem. The products will remove the unwanted background noise and interference, whether it originates from the transmission process, or is picked up from the environment by a microphone. There is a solution to suit most types of radio and voice communications equipment: There are noise elimination speakers that fit into the base station or mobile environment, in-line noise cancelling modules that can be integrated into the communication system, or noise eliminating pcb modules that can be retrofitted internally into existing equipment or designed into new products. The products work just as well in the microphone path, on the transmit side, or in the receive path, and can be used to clean up noisy voice recordings.
