Abstract

Abstract A sound reflector-modifier particularly useful to the hard of hearing for improving the quality and clarity of sounds received and reproduced by hearing aids and comprising in combination a sound reflective surface for receiving direct sound waves from a source and for reflecting them into an enlarged end of a sound passage leading to a sound chamber communicating with a sound pickup of a hearing aid.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 305 words
A hoLlow generally ear-shaped sound reflector-modifier for capturing only reflected sound waves rebounding from an immediately adjacent sound reflective surface and for directing the captured reflected sound waves to a hearing aid microphone enclosed in a case in a manner which increases the fidelity and clarity of the sound waves, comprising: a first housing portion including outwardly and forwardly depending sides facing said sound reflective surface, an upper edge directed toward said sound reflective surface with a forward upper lip immediately adjacent thereto, a front face below said upper edge facing said sound reflective surface and relieved below said upper lip away from said sound reflective surface, and a back face rearward of said front face for shielding said front face from direct sound waves from a source rearward of said back face whereby said front face combines with said sound reflective surface to form a chasm for capturing only reflected sound waves rebounding from said sound reflective surface; a second housing portion extending from said first housing portion; means for mounting said second housing portion on said case over an aperture open to said microphone such that the microphone is shielded from said direct sound waves from said source; and sound passageway means for directing the captured reflected sound waves from said chasm to said microphone while increasing the fidelity and clarity of said reflected sound waves, said passageway means having a first open end in said front face immediately below said upper lip and comprising substantially the entire area of said front face for receiving sound waves rebounding from said sound reflective surface, a second open end in said second portion over said aperture open to said microphone, and means defining a substantially spherical quadrant-shaped member in said second portion including said second open end and an opening to said sound reflective surface.
Claim 2
Dependent Claim 305 words
A hoLlow generally ear-shaped sound reflector-modifier for capturing only reflected sound waves rebounding from an immediately adjacent sound reflective surface and for directing the captured reflected sound waves to a hearing aid microphone enclosed in a case in a manner which increases the fidelity and clarity of the sound waves, comprising: a first housing portion including outwardly and forwardly depending sides facing said sound reflective surface, an upper edge directed toward said sound reflective surface with a forward upper lip immediately adjacent thereto, a front face below said upper edge facing said sound reflective surface and relieved below said upper lip away from said sound reflective surface, and a back face rearward of said front face for shielding said front face from direct sound waves from a source rearward of said back face whereby said front face combines with said sound reflective surface to form a chasm for capturing only reflected sound waves rebounding from said sound reflective surface; a second housing portion extending from said first housing portion; means for mounting said second housing portion on said case over an aperture open to said microphone such that the microphone is shielded from said direct sound waves from said source; and sound passageway means for directing the captured reflected sound waves from said chasm to said microphone while increasing the fidelity and clarity of said reflected sound waves, said passageway means having a first open end in said front face immediately below said upper lip and comprising substantially the entire area of said front face for receiving sound waves rebounding from said sound reflective surface, a second open end in said second portion over said aperture open to said microphone, and means defining a substantially spherical quadrant-shaped member in said second portion including said second open end and an opening to said sound reflective surface.
Claim 3
Dependent Claim 44 words
The sound reflector-modifier of claim 1 further including in said second housing portion sound wave deflecting louvers inclined relative to the direction of reflected sound waves rebounding from said sound reflective surface into said chasm for directing said reflected sound waves toward said aperture.
Claim 4
Dependent Claim 310 words
A hollow generally ear-shaped sound reflector-modifier for increasing the fidelity and clarity of sound waves received by a hearing aid microphone housed in a case supported against the chest of its wearer, comprising: a lower housing adapted for mounting on said case over an aperture leading to said microphone to shield said microphone from direct sound waves; an upper housing extending upward from and forward of said lower housing toward said chest and including an upper edge having a forward upper lip engaging said chest, a front face below said upper edge facing said chest and relieved below said upper lip away from said chest, and a back face rearward of said front face for shielding said front face from direct sound waves from a source rearward of said back face whereby said front face combines with said chest to form a chasm for capturing only reflected sound waves rebounding from said chest; and a passageway through said upper and lower housings for directing the captured reflected sound waves from said chasm to said microphone while increasing the fidelity and clarity of said reflected sound waves, said passageway having a first open end in said front face immediately below said upper lip and comprising substantially the entire area of said front face for receiving sound waves rebounding from said chest, a second open end axially displaced about 90* from said first open end and being in said lower housing over said aperture in said case, an axially elongated funnel-shaped upper passage portion including said first open end and extending therefrom rearwardly and downwardly to an intermediate passage portion of relatively small cross-sectional area, and a lower passage portion extending from said intermediate passage portion in said lower housing and including said second open end and having a shorter axial length and a smaller cross-sectional area than said upper passage portion.
Claim 5
Dependent Claim 310 words
A hollow generally ear-shaped sound reflector-modifier for increasing the fidelity and clarity of sound waves received by a hearing aid microphone housed in a case supported against the chest of its wearer, comprising: a lower housing adapted for mounting on said case over an aperture leading to said microphone to shield said microphone from direct sound waves; an upper housing extending upward from and forward of said lower housing toward said chest and including an upper edge having a forward upper lip engaging said chest, a front face below said upper edge facing said chest and relieved below said upper lip away from said chest, and a back face rearward of said front face for shielding said front face from direct sound waves from a source rearward of said back face whereby said front face combines with said chest to form a chasm for capturing only reflected sound waves rebounding from said chest; and a passageway through said upper and lower housings for directing the captured reflected sound waves from said chasm to said microphone while increasing the fidelity and clarity of said reflected sound waves, said passageway having a first open end in said front face immediately below said upper lip and comprising substantially the entire area of said front face for receiving sound waves rebounding from said chest, a second open end axially displaced about 90* from said first open end and being in said lower housing over said aperture in said case, an axially elongated funnel-shaped upper passage portion including said first open end and extending therefrom rearwardly and downwardly to an intermediate passage portion of relatively small cross-sectional area, and a lower passage portion extending from said intermediate passage portion in said lower housing and including said second open end and having a shorter axial length and a smaller cross-sectional area than said upper passage portion.
