Sirens and alarms play an important role in everyday life since they warn people of
hazardous situations, even when these are out of sight. Automatic detection of this class of …

The paper undertakes an extensive and critical review of published works concerning the
state of the art in safety systems based on building information modelling (BIM). It finds that …

To explore the behavioural and cognition patterns of fighter pilots under visual and verbal

This paper presents a real-time voice activity detection (VAD) algorithm implemented in a
miniature Digital Signal Processor (DSP) for in-ear listening devices such as earphones or …

Headphones are commonly used in noisy environments. Insert headphones attenuate and
color the spectra of ambient sounds and thus alter the auditory perception. When the …

Electronic hearing protection devices are increasingly used in noisy environments. Theses
devices feature a miniaturized external microphone and internal loudspeaker in addition to …

A large number of alarm sounds triggered by biomedical equipment occur frequently in the
noisy environment of a neonatal intensive care unit (NICU) and play a key role in providing …

In this paper, a single-channel speech enhancement algorithm based on non-linear and
multi-band Adaptive Gain Control (AGC) is proposed. The algorithm requires neither Signal …

Perception of warning sounds, such as vehicle backup alarms, is reduced when hearing
protection devices (HPDs) are worn. A cross-correlation approach is employed to detect a …
