Abstract

Путем цифровой фильтрации (18) одного или более сигнальных источников в соответствии с выбранными моделями и параметрами обработки сигналов с цифровым управлением, включая источники аудиосигналов, пространственные координаты пространственного распространения, акустические границы, сигналы, представляющие один или более имитируемых слуховых аппаратов и индивидуальные передаточные функции "тело/наружное ухо", синтезируется имитируемый трехмерный акустический режим для воспроизведения его для человека с нарушением слуха (20) для объективной и субъективной количественной оценки слуха посредством внутриканального протеза (22), который располагается в слуховом проходе (21) и включает микрофонный зонд для измерения чувствительности в слуховом проходе в общей опорной точке рядом с барабанной перепонкой (26) во время количественной оценки слуха без слухового аппарата, с имитируемым слуховым аппаратом и при наличии слухового аппарата. Виртуальный электроакустический аудиометр (19) вычисляет электроакустические параметры слухового аппарата на основе результатов аудиометрической оценки без слухового аппарата и эталонных измерений, которые включали в себя акустическую чувствительность рядом с барабанной перепонкой. Затем система синтезирует акустические сигналы, отражающие комбинированный выбор модели аудиосигналов, модели пространственного распространения, модели акустических границ, а также компьютерной модели слухового аппарата в случае режима имитации слухового аппарата.Международная заявка была опубликована вместе с отчетом о международном поиске.By digitally filtering (18) one or more signal sources in accordance with selected models and signal processing parameters with digital control, including audio sources, spatial coordinates of spatial distribution, acoustic boundaries, signals representing one or more simulated hearing aids and individual transfer functions " body / outer ear ", a simulated three-dimensional acoustic mode is synthesized to reproduce it for a hearing impaired person (20) for an object willow and subjective quantification of hearing by means of an intra-canal prosthesis (22), which is located in the ear canal (21) and includes a microphone probe for measuring sensitivity in the ear canal at a common anchor point near the eardrum (26) during a quantitative assessment of hearing without a hearing aid with a simulated hearing aid and with a hearing aid. A virtual electroacoustic audiometer (19) calculates the electroacoustic parameters of a hearing aid based on the results of an audiometric evaluation without a hearing aid and reference measurements, which included the acoustic sensitivity near the eardrum. The system then synthesizes acoustic signals reflecting the combined selection of the audio signal model, the spatial distribution model, the acoustic boundary model, and the computer model of the hearing aid in the case of a hearing aid simulation. The international application was published along with an international search report.
