About the talk:
BS 4142 provides subjective and objective methods for determining graded corrections to the specific sound level for impulsivity and tonality; however, these require specific sound sources to be installed and operating. In planning applications where the sources are proposed, or the propagation path is intended to change significantly, only the professional judgement of the acoustics practitioner can be relied upon to determine the likely prominence/audibility of these features at a remote assessment location. To address this gap, simplified auralisation (‘auralisation-lite’) has been used to estimate the character corrections using the calculation method from ISO 9613-2.
In this talk, the problem being addressed will be highlighted, the process of auralisation-lite will be described, the results of experiments testing the method will be presented, and an interactive test will be used to highlight the importance of objective methods.
