Abstract
A partial enclosure for inhibiting sound passing into and out of the partial enclosure includes an absorber-barrier or an absorber-barrier-absorber, each made from sound absorbing material and sound barrier material and arranged to form the partial enclosure. The enclosure also includes an adaptive frequency matched sound-masking system. The absorber-barrier or absorbed-barrier-absorber is positioned to block or inhibit unwanted sound from various positions of a source of the unwanted sound, or motion of the source of the unwanted sound. The adaptive frequency matched sound-masking system includes a sound generating device arranged on or in the partial enclosure to emit anti-noise signal to cancel or inhibit the unwanted sound.
Claims24
1-18. (canceled)
A noise reducing system, comprising:
- an acoustic partial enclosure constructed with a sheet of an acoustic material formed with at least one sound absorbing layer that has sufficient transmission loss to reduce noise going in or coming out of said partial enclosure so that said noise is no longer a significant disturbance;
- said acoustic partial enclosure configured to block or inhibit unwanted sound from entering said acoustic partial enclosure from a source of said unwanted sound located proximate the partial enclosure, or from a source of the unwanted sound inside the partial enclosure even if the source is moving and as the moving source moves proximate the partial enclosure;
- and
- wherein the opening of the acoustic partial enclosure is sufficiently large to allow airflow necessary for an animal to breathe, but small enough to significantly reduce the number of direct noise paths entering or exiting the partial enclosure.
A noise reducing system, comprising:
- a partial enclosure having an opening having a size is sufficient to allow airflow for breathing but small enough to restrict at least some direct acoustic wave noise paths,
- said opening having an edge that holds at least one speaker and at least one microphone of an adaptive frequency matched sound masking or active noise canceling system, wherein the system is configured to be tunable to the preferences of the user;
- wherein the partial enclosure is formed of a sheet of at least one of an absorber material, absorber-barrier material, and absorber-barrier-absorber material positioned to block or inhibit unwanted sound from a source of the unwanted sound located proximate the partial enclosure, or from a moving source of the unwanted sound as the moving source moves proximate the partial enclosure;
- and
- wherein the adaptive frequency matched sound-masking or active noise canceling system includes at least one sound generating device arranged at least one of a position on, near, and in the partial enclosure to serve as a cancelling sound source from which an anti-noise signal generated by the adaptive frequency matched sound masking or active noise canceling system is output to effect sound-masking or active noise canceling of the unwanted sound.
