Acoustically transparent visor

A sun visor for use with a motor vehicle includes a visor body having sufficient acoustic transmissibility such that the visor body is sufficiently sound transparent. The visor body further being sufficiently opaque so as to inhibit passage of light through the visor body.

Multiple source auralization progress report

The problem of accurate spatial representation of large orchestras in binaural auralizations is attacked by convolving anechoic recordings of individual instruments with the room impulse responses simulated from each instrument location to a single listener location and subsequently mixed. Instrument directivity and power, orchestra member effects, individual pinna transfer functions, and headphone transfer functions are considered. Progress, techniques, limitations, and problems of this current research will be discussed. [Research supported by The Talaske Group, Inc.]
