A criterion for the maximum permissible magnitude of repetitive pressure pulses of the type likely to be experienced in the Channel Tunnel (TR-PHYS-1)

Experiments have been performed in a pressure cell to determine a comfort criterion for the regular pressure pulses that will be experienced in the Channel Tunnel. Twenty-eight subjects experienced eight conditions of pressure excursion and time interval between pulses. It was found that the desirable maximum level of pressure excursion...
