Fisher Whisper III FeaturesFisher Whisper III FeaturesFisher Whisper III FeaturesFisher Whisper III Features• The trim uses series of parallel

passages to ensure jets independence and prevent additional noise.

• Frequency shifting: Higher frequencies are less problematic to hearing and process systems

• Complementary body design to prevent secondary noise sources


prevent secondary noise sources• Characterize trim to accommodate

the cage for different scenarios during travel

CAPTION: Computational fluid dynamics show jet inde pendencefrom three properly spaced holes (left). The same t hree holesspaced too closely (right) show jet interaction, wh ich leads toadditional noise. Being able to predict and control jet interactioncan reduce the noise produced by up to 40 dBA. Corr ect sizing and selection of the appropriate trim allows for th is reduction
