Three experiments explored the resistance to simulated reverberation of various cues for selective attention. Listeners decided which of two simultaneous target words belonged to an attended rather than to a simultaneous unattended sentence. Attended and unattended sentences were spatially separated using interaural time differences (ITDs) of 0, +/-45, +/-91 or +/-181 micros. Experiment 1 used ...

The goal of this paper is to compare the results of reverberation time measurements obtained with different well-established methods used for this type of measurements, as well as some additional ones which could serve as in situ tool when standard methods are not available. The methods compared in this paper include integrated impulse response measured with pink noise, exponential sweep and ML...

When we speak in an environment with noise, we often modify our speech production, and speech spoken in noise is generally more intelligible than speech produced in a quiet environment, which is known as the Lombard effect. Our goal is to provide intelligible speech announcements in noisy and/or reverberant public spaces, such as train stations. Thus, the present paper examines whether speech s...

Determination of the rate of energy loss in a reverberation chamber is fundamental to many different measurements such as absorption cross-section, antenna efficiency, radiated power, and shielding effectiveness. Determination of the energy decay time-constant in the time-domain by linear fitting the power delay profile, rather than using the frequencydomain quality-factor, has the advantage of...

This paper introduces a time-variant reverberation algorithm as an extension of the feedback delay network (FDN). By modulating the feedback matrix nearly continuously over time, a complex pattern of concurrent amplitude modulations of the feedback paths evolves. Due to its complexity, the modulation produces less likely perceivable artifacts and the time-variation helps to increase the livelin...
