In the spirit of SG Brown, Racal Acoustics continued to develop and find innovative solutions to new challenges. Today the technology is embedded in international standards, which stipulate that headsets must also protect hearing – while maintaining the user’s situational awareness. This is particularly important in military vehicle environments where the noise level is high.
Racal Acoustics developed the first analogue, electronic Active Noise Reduction (ANR) headset – adapted for military use. The company was also behind the development of electronic “hear through”, a further development of the conventional mechanical valve technology. In the mid 2000’s, analogue and digital technologies started to be combined, enabling the addition of software functionality. This in turn enabled easier integration into the customer’s systems and solutions.
Continuing investment in product development has made it possible to develop platforms based on Digital Signal Processing (DSP). This technology allows customized solutions, including ANR profiling to specific vehicles, to be implemented throughout the lifetime of the headset without the need for costly hardware upgrades, thus reducing life-cycle costs.
Military communications equipment has become increasingly digital, which presents opportunities to use 3D sound technology. This is used in the latest headsets from Racal Acoustics, allowing the user to listen to eight audio channels at the same time, compared with two or three channels, which is the limit for conventional technology.
