  • Our sales, design, engineering and project teams will work as an extension of your team to deliver industry-leading noise protection. (durisol.com)
  • Appropriate sound quality models for noise-induced discomfort are necessary for a better acoustic comfort design in the aircraft cabin. (bvsalud.org)
Study4
  • In this study the acoustic velocity, and hence the temperature, is derived in an interferometric approach from hydrophone array recordings. (knmi.nl)
  • We study the effect of noise in the density field, such as would arise from a finite number density of tracers, on reconstruction of the acoustic peak within the context of Lagrangian perturbation theory. (escholarship.org)
  • This study investigates the acoustic discomfort in two large passenger aeroplanes (i.e., planes A and B). We recorded the noise at 21 positions in each aircraft cabin and selected 42 stimuli ranging from 72 to 81 dB(A) during the cruising flights. (bvsalud.org)
  • The findings also echo a somewhat larger body of work looking at traffic noise, including the large HYENA study. (medscape.com)
Services1
  • New development projects often require an acoustic report and related services during the approval, construction and assessment phases to ensure compliance with local government and state requirements. (ghd.com)
