What critical regulatory achievement did Sennheiser secure with its NoiseGard technology in 1987?

Answer

FAA Technical Standard Orders (TSO) certification for mass manufacturing.

Sennheiser’s approach to the aviation market focused heavily on regulatory compliance and safety validation, running concurrently with Bose's broader technology development. After being commissioned by Lufthansa, Sennheiser developed the NoiseGard technology, which debuted in the LHM 45 headset in 1987. The significant milestone achieved by this product was securing the FAA Technical Standard Orders (TSO) certification. This certification was vital because it validated the headset’s design and manufacturing process for mass deployment in the safety-critical aviation sector, providing Sennheiser an early authoritative foothold in that specific professional market.
