A stringed instrument such as a guitar with a thinner than traditional body is provided enhanced decibels measured by sound pressure level (DBSPL) response employing a combination of one or more of each of a passive radiator, tuned isolated resonating wave guide or guides in the body cavity and an equalized closeable sound opening in the front face configured to maximize volume at low frequencies and increasing low frequency response, e. g. , at or less than 500 Hz. The passive radiator may be in either the front or rear or both faces. The wave guides each comprise elongated sheets in the body chamber spaced from the corresponding face by spaced posts. The wave guides may be in opposing cooperating pairs or may be staggered for directing low frequency waves to a sound opening in the front face and resonate to provide enhanced low frequency response and subsequent volume. The passive radiator in the rear face is recessed within the body chamber.

The purpose of the invention is to direct, in a coherent fashion, audible frequencies, particularly, low frequencies and especially those below 90 cycles. The advantage to directing low frequencies to acute projection patterns previously thought impossible is to reduce low frequency feedback in live performance applications and to reduce low frequency room reverberation in all applications which results in a faster decay time of the low frequency produced. Acute directivity of low frequencies is achieved by using a rectangular enclosure in the vertical axis and by placing a rectangular port on the horizontal axis centrally located between two transducers. The three-point projection pattern is established so that the three points of projection can act to set up a carrier wave and side band waves effect. Alternatively, one transducer can be centrally located between two rectangular ports.

The present invention relates to an acoustical transducer enclosure which is particularly adapted for directing sound waves and is housed in a multisided enclosure. The enclosure has a cylindrical hollow tube, held in position by a pair of forward baffles, with a speaker housed within. Forward wave guides line the interior area of the enclosure. A wave form vent is located on a horizontal plane with the speaker at one end of the cylindrical hollow tube. A rear back pressure booster baffle is located at the end of the cylindrical hollow tube with a wave splitter which is located proximate the rear back pressure booster.

A protective wound bandage which allows for the body's natural epitheliazation process to be enhanced by the function of said bandage in the following ways. A non-stick surface is provided to make contact with the wound. An absorbent pad is provided for body fluid drainage. The skin adhesive surfaces of the flexible plastic strip which can be made to any dimension, in combination with the pad act to protect and cohesively and coherently bind the wound edges together. The removably, reattachable, tear tab provides the ability to regulate and monitor oxygen flow to the injury site. The pad, in either the standard or perforated form acts to protect against shock and also acts as an medicant delivery system. The bandage acts as a medicant delivery system and is also simultaneously, variably, oxygenatable. The bandage is engineered to operate in either the dry or medicated versions.

A protective dressing consisting of a two sided plastic strip, with a first, a second and a third portion. The second portion has a removably affixed perforated cover on one side and a gauze layer, a thick absorbent pad and a non-stick layer on the other side. The perforated cover can be removed and reaffixed to allow for increased or decreased oxygenation.
