Audibility of coincidence dips and structural resonance dips in acoustic isolation curves
The audibility of coincidence dips and structural resonance dips in acoustic isolation curves of different types of walls is investigated. Measured and simulated wall transmission curves with varying dip magnitude and central frequency are emulated in listening tests by presenting simulated sound on the receiving side of a wall, which originates from sending realistic sound pressure level pink noise through a wall and by applying its transmission curve as a filter. Differences in dip magnitude of 1.5 dB and more are found to be audible. Shifting the central frequency of the dip from 400 Hz to 500 Hz or from 1600 Hz to 2500 Hz is clearly audible.
