Abstract

An acoustic hearing aid comprising: (a) a pair of thick-walled, sound collector cups (12) each shaped to fit over the pinna (20) of a user's ear, turning the back of pinna (21) forward, and each constructed of a sound reflective material of sufficient thickness to provide insulation against sound transmission therethrough from a side (19) of collector cups (12), collector cups (12) each having a C-shaped ridge (17) of substantial thickness dimension formed for engagement of the user's head immediately proximate and around the user's pinna (20), ridge (17) extending from a position in front of the top of pinna (20) and above the level of ear canal (22) around pinna (20) to a position below earlobe (23), collector cups (12) each further extending outwardly from ridge (17) and away from the user's head and extending forwardly in a generally parallel relation to the user's head to a position in advance of ear canal (22) to reduce sound transmission to the user's ears from the sides of the user's head, collector cups (12) each terminating in a forwardly facing, substantially vertically oriented, generally rectangular opening (25) for receipt and collection of sound emanating from the front of the user; and (b) an arcuate headband (14) constructed of a resiliently flexible material and having collector cups (12) mounted proximate opposite ends thereof, headband (14) being dimensioned to apply a resilient biasing force to collector cups (12) to bias C-shaped ridge (17) into contact with the user's head proximate the user's ears to transmit collected sound vibrations through C-shaped ridge (17) to the user's bone structure proximate the ears and resist the entry of sounds other than from in front of the user from entering said collector cups.
