Filed:

Sep 16, 2005

Appl. No.:

11/229058

Inventors:

Ronald R. Freiheit - Owatonna MN, US

Assignee:

Wenger Corporation - Owatonna MN

International Classification:

E04B 1/343
E04B 1/99

US Classification:

181287, 181 30

Abstract:

An electroacoustic shell system adapted create a performance area where sound created by a performer is received, processed, and returned to the performer in the performance area. The system broadly includes an electroacoustic shell with a vertical panel and a canopy, a microphone and a speaker operably coupled to the shell, and an electronics processing assembly connected to the microphones and speakers for recording, broadcasting, and simulating sound.

US Classification:

181198, 181 30, 181210, 181194, 181284

Abstract:

The present invention is an acoustic cabinet for the storage of musical instruments. Acoustic cabinet can have a storage portion having a plurality of individual storage units contained therein. One or more grill doors can cover the open end of acoustic cabinet. The size, shape, and arrangement of grill bars of door can be configured to reduce the effect of resonance. Rear panel of acoustic cabinet can include one or more sound-absorbing panels that absorb sound as it passes through acoustic cabinet. A protective backing can also be disposed between sound-absorbing panels and individual storage spaces to protect the panels from damage when instruments and other objects are inserted into the storage spaces. A combination of a grill door and sound-absorbing panels can allow acoustic cabinet to have a net-absorptive effect on a rehearsal room. One or more acoustic cabinets can be strategically positioned throughout a rehearsal room for optimal acoustic performance.

10/934650

Inventors:

Ronald Freiheit - Owatonna MN, US

International Classification:

H03G003/00
H02B001/00

US Classification:

381061000, 381123000

Abstract:

A system for sharing acoustical signal control among acoustical virtual environments generally includes a number of acoustic performance modules, a single acoustical system, and a switchable, single control system. The switchable single control system is interfaced to each of the acoustic performance modules and is operably connected to the single acoustical system. The control system is switchable to one of the acoustic performance modules whereby acoustic signals are able to flow between the performance module and the acoustical system; acoustic signals between all other performance modules and the acoustic system are blocked.

Assignee:

Wenger Corporation - Owatonna MN

International Classification:

E04B 199

US Classification:

181 30

Abstract:

A rehearsal room especially adapted to produce the auralization effect of different acoustical environments. The rehearsal room broadly includes a performance space defined by a plurality of walls, each of the walls including a plurality of acoustical absorption panels, a floor and a ceiling, a plurality of microphones operably coupled to the ceiling at predetermined locations, a plurality of acoustical speakers operably coupled to the ceiling at predetermined locations relative to the position of the microphones and speakers; and an electroacoustic system connected to the microphones and speakers for recording, broadcasting and simulating sound.

International Classification:

E04B 1/99
E04B 1/86

Abstract:

A tunable acoustic panel that functions as an acoustic diffuser and absorber is disclosed. The acoustic properties of the tunable acoustic panel can be quickly and conveniently modified by moving a handle. The tunable acoustic panel is wall-mountable for use as an acoustical room treatment to selectively vary the acoustical response of a room or performance space.
