1 The noise emissions from the operation of heliports situated in cities can have significant adverse impacts on a large number of local residents. Despite its significance this topic is under studied. This paper presents the subjective part of a novel study on the noise emissions and associated impact from the Lon-don (UK) heliport operation. The...

This pilot study uses the opera singers from the Royal Academy of Music to investigate first: the impact of acoustics on opera singers' vocal load levels to determine if acoustic modifications to the rehearsal rooms could reduce the vocal stress placed on the singers; second: the noise dose the singers are exposed to during their daily practices. M...

... Results were compared in terms of reverberation times to establish the effect of the source type on the room response and assess the feasibility of substituting source types with alternatives when necessary, or simply when more practical to do so (also see [10,11]). Considering the measured data it can be deduced that the majority of the test rooms produced a primarily diffuse sound field for the higher frequency range, with the partial exception of room 10. Table 4 shows the standard deviation for the T 30 and EDT variation among the four source configurations as an average over all receiver positions in a room. ...

... In contrast, the digital simulations allow acoustic predictions in all points of a space; however, the calculations cannot take into consideration the phonemes, along with the nonstationary sound source that represents a voice [36], which leads to a simplification and optimization of the results compared to the measurements [37,38]. In addition, the listening tests to which the students were subjected may be limited to the selection of the adopted criteria [39,40]. ...
... To solve this problem a collaboration was formed with Audio 3 to develop a very lightweight, 35 g, rechargeable dosimeter and class 2 sound level meter, see figure 15 13 . The commercial version of this device is currently being used to measure the noise exposure of opera singers 14 . ...
