The use of corrugation provides an inexpensive and manner of forming a plurality of highly effective acoustic attenuation channels throughout the mechanism. The multi-layered mechanism may be provided in a variety of modular forms and sizes which may be combined to form a low-cost, highly effective attenuation housing. For example, such a housing may be utilized to contain otherwise noisy large scale oilfield equipment such as coiled tubing engines. Additionally, where drainage from the housing is sought, a spiraled attenuation channel may be employed such that the effectiveness of the attenuation provided by the housing is not sacrificed.

  • Publication number: 20130017755
    Abstract: A call maker typically bores a sound channel from the exhaust port end of the insert through the bell all the way through the insert. A newer innovation was to drill the sound channel to a specific depth in the sound board, but stopping before reaching the tip of the sound board, thus creating back pressure and making the call easier to blow. By drilling the sound channel to just past the seat line, a call maker may then complete the shaping of the sound channel after the forming of the sound board using an end mill to cut a precisely shaped channel with controlled angle, depth, and width to adjust the proper root back pressure and finely tune the call's tone and quality in a replicable manner.

  • Publication number: 20120314882
    Abstract: The invention is intended to facilitate the production of ambient noise- cancelling earphones and, to that end, provides a module (30) comprising a microspeaker (34) and an electret microphone (38) both carried on a common substrate (32) which is also configured to incorporate an acoustic resistor (33, 35). The module (30) is incorporated into an earpiece having electrical connections to noise-cancelling electronic circuitry that is provided separately from the earpiece and is housed, for example, in a separate pod (82, 102) or incorporated within the body of a cellular telephone. The performances of the microspeaker (34) and microphone (38) are classified against one or more predetermined operational criteria, enabling the noise-cancelling circuitry to be configured to allow for departures from such criteria.

  • Publication number: 20120294472
    Abstract: The present invention relates to a loudspeaker assembly and a method of assembling a loudspeaker assembly. In one or more embodiments, the invention comprises forming a front baffle comprising a first driver mounting portion, an intermediate portion, and an edge mounting portion. A first driver is installed in the first driver mounting portion proximate to a first driver aperture. A rear baffle is formed from a second material, which, in one or more embodiments, is less stiff than the first material from which the front baffle is formed. The rear baffle comprises a top portion, sidewalls, a recessed mounting portion, and an edge portion. The edge mounting portion of the front baffle is attached to the recessed mounting portion of the rear baffle such that an entirety of said front baffle is recessed within said rear baffle spaced apart from said open bottom portion.

    Abstract: A firearm suppressor device with improvements over the prior art is disclosed. In some embodiments, the firearm suppression comprises a sleeve, first and second end caps, a sacrificial block, and a suppression insert. The first and second end caps may removably attachable to the sleeve, for example, by compatible threading on the end caps and the sleeve. The first or second end caps may also comprise means to facilitate removal of the end cap from the sleeve, for example, a knurled finish to increase friction with a user's hand. Some embodiments of the firearm suppressor device may be used for different types and caliber of firearms, such as pistols and rifles.

  • Patent number: 8238565
    Abstract: A system for adapting a hearing aid to a user includes a unit generating an image of the user's ear together with a model of the hearing aid, wherein the model of the hearing aid in-situ includes a physical model of the hearing aid inserted in the user's ear prior to generating the image. The system also generates a mesh based on the image, calculates acoustic response to a simulated acoustic signal in the mesh, calculates a frequency response curve for a fixed position in the mesh, and identifies an optimal position of a microphone of the hearing aid in-situ from the acoustic response. They system also includes a comparator configured to compare the frequency response curve for the fixed position in the mesh with a maximum frequency response curve for the mesh stored by the system.
