Acoustic Characterization of a Room: Study Case Between Simulation and a Portable Method
Archives of Acoustics, 2020 Large venues and auditoriums are commonly associated with their astounding architecture. Their acoustic quality is an essential factor in its qualification as a great and functional, or a badly designed place.

Noise Source Identification in Training Facilities and Gyms
Applied Sciences, 2021 This paper deals with noise problems in industrial sites adapted for commercial training venues. The room acoustics of such an object were analyzed in the scope of the reverberation time and potential acoustic adaptation measures are indicated ...

The Acoustical Performance of Rooms [PDF]
The Journal of the Acoustical Society of America, 1948 It is appreciated that the reverberation characteristic is only one measure representing the acoustical performance of a room. Measurements have been made on a number of average size studios and rooms using techniques other than reverberation measurement. Equipment has been constructed to produce an audio signal varying continuously in frequency and in

Inverting non-minimum phase FIR transfer functions [PDF]
, 2013 The approximate solution to the inverse of a non-minimum phase finite-impulse response (FIR) transfer function is given. Such a problem arises in many areas which include room-acoustics and channel equalisation.

Acoustical Science and Technology, 2020 : Speech signals can be represented as a sum of amplitude-modulated frequency bands. This sum can also be regarded as a temporal amplitude envelope (TAE) with temporal fine structure.

Advanced Engineering Materials, EarlyView.Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

Advanced Engineering Materials, EarlyView.The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...
