About this opportunity
The Naval Facilities Engineering Command awarded a $368,463 research contract to the National Marine Mammal Foundation to determine the extent to which the equal energy hypothesis can accurately predict temporary threshold shifts for long-duration tonal exposures simulating continuously active sonar over periods ranging from 7.5 to 60 minutes. The contract also requires examining whether linear frequency modulation common to continuously active sonar reduces temporary threshold shift effects relative to continuous wave tones at equal sound exposure levels, with research to be conducted from 2 November 2021 through 31 December 2023.
Notice text
The purpose of this requirement is for a research project to determine the extent to which the equal energy hypothesis accurately predicts temporary threshold shifts (TTS) for long-duration tonal exposures with qualities simulating continuously active sonar (CAS) in support of Naval Facilities Engineering Systems Command (NAVFAC) Engineering and Expeditionary Warfare Center (EXWC), Environmental, Living Marine Resources Program.
This project will determine the extent to which the equal energy hypothesis can be used to predict TTS for exposures ranging from 7.5 to 60 minutes. This project will also determine if linear frequency modulation common to CAS reduces TTS effects relative to continuous wave tones with equal sound exposure level.
The Period of Performance is from 2 November 2021 to 31 December 2023.
Awarded contract N39430-22-C-2400 to NATIONAL MARINE MAMMAL FOUNDATION, INC. for 368463.00 on 2021-11-02.
