AbstractThe Cocktail Party Effect refers to the ability of the human sense of hearing to extract a specific target sound source from a mixture of background noises in complex acoustic scenarios. The ease with which normal hearing people perform this challenging task is in stark contrast to the difficulties that hearing-impaired subjects face in these situations. To help patients with hearing aids and implants, scientists are trying to imitate this ability of human hearing, with modest success so far. To support the scientific community in its efforts, we provide the Bern Cocktail Party (BCP) dataset consisting of 55938 Cocktail Party scenarios recorded from 20 people and a head and torso simulator wearing cochlear implant audio processors. The data were collected in an acoustic chamber with 16 synchronized microphones placed at purposeful positions on the participants’ heads. In addition to the multi-channel audio source and image recordings, the spatial coordinates of the microphone positions were digitized for each participant. Python scripts were provided to facilitate data processing.

Acoustic Levitator

Acoustic contactless manipulation technique that is capable of transporting and manipulating of small particles is highly attractive in studying of many physical phenomena and biochemical processes. The finite element method is used to study the effect of the acoustic field geometric parameters on the acoustic levitator consisting of the transducer planar array and a reflector. The optimal acoustic chamber height and the distances between the array elements are determined through the numerical simulation. The analytical results provide the geometry parameters that can be used in optimizing acoustic chamber for particles transportation.

Abstract An active segmented trim panel for use as a secondary source for noise control in aircraft is designed, analyzed and tested. It consists of a rectangular segment of aircraft trim panel which is suspended by a flexible support. This support converts the stiff composite trim panel into flexibly-mounted pistons which can be driven by light-weight and low-profile force actuators. The active segmented trim panel offers an acoustic source of lower profile and lower mass, and requires only a simple modification of materials already installed on aircraft. This paper presents a summary of recent results of modeling and testing of an active trim panel configuration. Real-time noise control experiments are conducted using the active trim panels as secondary sources indicating that the present active segmented trim is a promising technology.
