“…Cochlear implants use electrical stimulation of the auditory nerve to simulate normal cochlear hearing [10]. First, the microphone on the outside machine converts the sound pressure change in the air into a voltage signal, the voltage signal is amplified and sampled and enters the speech processor (usually its core is a digital signal processing chip), the speech processor is responsible for encoding the obtained sampling signal (including acoustic signal coding and control instruction coding), and then the radio frequency transmission circuit modulates the coding result of the speech processor to the RF carrier signal (generally commercial frequency band is 5~50MHz range).…”

Hearing is the sound depiction of the world for human beings. The ear, or in other world, the peripheral organ of hearing, is an important physiological structure and basis to produce hearing. In order to learn more about hearing organs, the first thing required to know is how hearing is formed, as well as how sound is perceived by us. For this purpose, this paper will examine the matter of identification and processing of in-ear acoustic signals. The main content of this paper are principles of sound, hearing, and signal encoding, as well as their usage in a model which describes the neuron system in cochlear nucleus. In addition, this paper puts forward an application of in-ear signal identifying in hearing aids and cochlear implants by using the convolution signal encoding mode to improve the sound recognition function of these devices and further improve the lives of the hearing impaired. In the end, basic conceptions and related knowledge are organized in this paper. The meanings and problems of this paper are also mentioned in the last section.

Despite the growing use of cochlear implants in deaf patients, there is a lack of data on their knowledge, attitude, and practice (KAP) toward cochlear implants. This study aimed to investigate the KAP toward cochlear implants among deaf patients who received cochlear implants. A web-based cross-sectional study was conducted between August 2022 and December 2022 among deaf patients who had received cochlear implants. A self-administered questionnaire was used to collect demographic characteristics and KAP scores. A total of 526 participants were enrolled; 54.18% were female, 65.40% were above 60 years old, and 61.03% were surveyed at less than 3 years after implantation. The mean knowledge, attitude, and practice scores were 8.15 ± 2.18 (possible range: 0–10), 43.63 ± 6.98 (possible range: 12–60), and 41.11 ± 7.42 (possible range: 11–55), respectively, indicating good knowledge, moderate attitude and practice. Multivariable logistic regression analysis showed that attitude [odd ratio (OR) = 1.24, 95% confidence interval (CI) 1.18–1.29, P < 0.001] and unemployment (OR = 0.33, 95% CI 0.17–0.63, P = 0.001) were independently associated with practice. Path analysis showed that knowledge directly influenced attitude (β = 0.93, 95% CI 0.61–1.19, P < 0.001), attitude directly influenced practice (β = 0.53, 95% CI 0.46–0.61, P < 0.001), and knowledge directly (β = 0.77, 95% CI 0.53–1.01, P < 0.001) and indirectly (β = 0.50, 95% CI 0.34–0.66, P < 0.001) influenced practice. Deaf patients who received cochlear implants showed good knowledge, moderate attitude and practice toward cochlear implants. Knowledge should be strengthened to improve attitude and practice toward cochlear implants, which could translate into realistic expectations toward cochlear implants devices and proper care and maintenance.
