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 1.5dB and more are found to be audible.
Shifting the central frequency of the dip from 400Hz to 500 Hz or from 1600Hz to 2500Hz is clearly audible.
