StiffNeck is a tool for the auralisation of electroacoustic music performance venues based on measured room impulse responses. It has been developed to support in situ composition, a particular approach towards creating sitespecific electroacoustic music works. This compositional practice tries to take maximum advantage of the particularities of irregular loudspeaker configurations and their in...

Flexible and transparent graphene films have been fabricated via inkjet printing and vapor deposition (VDP) methods, and the graphene-based acoustic actuator could be used as an extremely thin and lightweight loudspeaker.

The paper deals with method and methodology for calibration of the whole microphone array without the need of dismounting of each microphone and calibrating separately. This situation is usual with MEMS transducers which cannon be dismantled from the frame. The method is based on generation of spherical acoustic wave propagating in free-field and synchronously received by all microphones in the...

Auditory cues, when coupled with visual objects, have lead to reduced response times in visual search tasks, suggesting that adding auditory information can potentially aid Air Force operators in complex scenarios. These benefits are substantial when the spatial transformations that one has to make are relatively simple i.e., mapping a 3-D auditory space to a 3-D visual scene. The current study...

Spherical loudspeaker arrays for directivity pattern synthesis of natural sound sources have been recently reconsidered in electro-acoustic research [3, 4, 5]. Quite some time after the pioneering works in that field [1, 2], multichannel hardware and computational resources are easy to obtain, and the design and control issues receive increased interest. The loudspeaker arrays considered here c...

Ideal loudspeakers produce acoustic waves, which are a linear transformation of the electrical input signal. In reality loudspeakers do produce nonlinear distortion as well. This paper presents a method to compensate this distortion in real-time by nonlinear digital signal processing, implemented on a Digital Signal Processor ( i . e . the TMS320C30 DSP). Based on literature, an electrical equi...

The sound pressure level (SPL) of the moving-coil loudspeaker (MCL) is often simulated and analyzed using the lumped parameter model. However, the SPL of a MCL cannot be simulated precisely in the high frequency region, because the value of cone effective area is changed due to the geometry variation in different mode shapes, it is also related to affect the acoustic radiation mass and resistan...

With the development of technology the whole dimension of communication has changed. In modern day people are more interested in hand-free communication. So, the users use an ordinary loudspeaker and a microphone, at place of telephone receiver. Benefit of wireless communication is that it allows the users to have both hands free and to travel freely in the area. The truth of a huge audio mixtu...
