Hearing protection and analysis

Multiple projects with the focus and aim on hearing protection and conservation have been conducted by Dr. Thomas Lagö. This includes hearing and sound impact/monitoring for health/medical applications. Dr Thomas Lagö has been the President of a USA company that was a high-end vendor in this industry. This experience, paired with multiple industrial research projects using Active Noise and Vibration Control and other means has created a unique foundation for future research and projects. One difficult application was the Super Puma helicopter used by the Swedish Marine. The picture depicts the challenging noise and speech intelligibility situation for the pilots and surface divers that needs to communicate constantly. The research work was aimed at signal processing systems enhancing the dynamic range and at the same time lowering the speech volume in the headsets. A combination of speech enhancement, ANC Narrowband and ANC Broadband was utilized (Active Noise Control) .
