Publication number: 20230188913Abstract: A system for validation of a hearing aid performance, especially in small children is disclosed. The validation of the performance of hearing aids after having being fitted to a small child who is not able to subjectively provide responses to sounds presented to the child via the hearing aids, is instead done in an objective manner, by using a naturally occurring signal, which has been modulated in order to create an ASSR evoking speech stimulus which is not considered as noise by a hearing aid.Type: ApplicationFiled: February 2, 2023Publication date: June 15, 2023Applicant: INTERACOUSTICS A/SInventors: Søren Laugesen, Bue Kristensen

Patent number: 7512245Abstract: In the method according to the invention a signal processing unit receives signals from at least two microphones worn on the user's head, which are processed so as to distinguish as well as possible between the sound from the user's mouth and sounds originating from other sources. The distinction is based on the specific characteristics of the sound field produced by own voice, e.g. near-field effects (proximity, reactive intensity) or the symmetry of the mouth with respect to the user's head.Type: GrantFiled: February 4, 2004Date of Patent: March 31, 2009Assignee: Oticon A/SInventors: Karsten Bo Rasmussen, Søren Laugesen

Patent number: 7477754Abstract: A method for counteracting the occlusion effect of an electronic device delivering an audio signal to the ear, like a hearing aid or an active ear protector, where the electronic device includes a transmission path with an external microphone or input line which receives a signal from the environment and an signal processor and a receiver which receives processes signal from the signal from the signal processor and delivers sound signals to the ear, whereby an ear piece is inserted into the ear canal and totally or partially blocks the canal. The sound conditions in the cavity between the ear piece and the tympanic membrane are directly or indirectly determined, and whenever condition leading to occlusion problems are determined, the transmission characteristics of the transmission path or the receiver changes in order to counteract the occlusion effect.Type: GrantFiled: August 7, 2003Date of Patent: January 13, 2009Assignee: Oticon A/SInventors: Karsten Bo Rasmussen, Søren Laugesen
