Common regulations were implemented such as lockdown, wearing face masks as mandatory, face shields, gloves and maintaining physical and social distance in public places to reduce the spread of the virus. These pandemic induced challenges affected social communication, technical and behavioral aspects in lifestyle of people with hearing impairment. Along with medical, paramedical services, the crisis had challenged hearing, speech language pathology and therapy services too. The study aimed to explore the challenges that adults with hearing impairment had experienced during the pandemic and to suggest some practical solutions that can be implemented by audiologists. It is a questionnaire-based study with purposive sampling method employed in data collection. The questionnaire was administered on adult hearing aid users (mean age: 18 years) recruited for participation from different parts/ clinical setups across India. The outcome of the questionnaire did support the assumption that availing audiological services was difficult or impossible for most of the hearing aid users. Accessing batteries was reported to be the most frequent issue. Adequate level of hearing though hearing aid was important to them and clinical services could not be availed for long period of time due to travel related issues and closure of audiological services. Also, social isolation impacted on their quality of life and effective communication. As a possible solution most of the users chose tele services as a better solution.

Thus, the objective of the study was to compare between Ms and non-musicians (NMs) and correlate the frequency resolution skills with years of musical experience, the difference limen for frequency (DLF), and the Q10 values of psychophysical tuning curves (PTCs) measured at 2 characteristic frequencies (CFs), 1000 and 4000 Hz. The secondary objective was to find out whether spontaneous otoacoustic emissions (SOAEs) can be recorded among Ms more frequently than among NMs. Methods: Thirty-six listeners with normal hearing participated in the study. They were 18 Ms with a minimum of 8 years of musical experience, and 18 NMs. Forward-masked PTCs and DLF tests were assessed for each listener in the right ear at 2 CFs, 1 and 4 kHz, and SOAEs were measured using standard protocol. Results: The results obta...

Everyday noises in an individual's own acoustic environment is a heterogeneous group and dynamic in that it changes throughout the day as well over a period of days/months. Therefore impact of these everyday noises on speech perception in individuals with normal hearing and hearing impairment is not easy to predict from clinical measures of word recognition scores. Effect of noise on word recognition score (WRS) is routinely measured using Speech in noise (SPIN) test, where in the competing signal is the audiometric noise. Hence, the present study aims to assess speech perception of an individual with hearing loss as measured using recorded noises which are representative of typical noises encountered by these individual's in their daily routine. The participants included 15 adults with bilateral mild to moderate hearing loss in the age range of 30-50 years. Detailed Audiological evaluation was carried out on all participants prior to the study to ensure compliancy to the selection criteria. Real world noises were recorded at locations which are frequented by the subjects in their daily life. This was done by a prior study (Sreelekha, 2014) using survey and questionnaire tool and all daily acoustic environment were tabulated on a frequency measure. Recording of these reported real world noises was done using a Sound Level Meter (SLM) with a condenser microphone connected to a laptop computer and software for audio recording. The speech perception was measured by using standard phoneme perception test in kannada (devaki..) and mixing these noise levels to the test materials at predetermined SNR level, i.e 0dB and +10dB SNR (Signal to Noise Ratio). Results: Results showed that certain noises like traffic noise effectively reduced speech perception ability more significantly than other noises. The effect was more for 0dB SNR than for +10dB SNR. The result suggests that not only overall amplitude of noise spectrum, the spectro-temporal distribution of energy also plays a key role in masking the cues for consonant perception of hearing impaired individual. The results of the current study reflects the importance of auditory ecology in understanding the acoustical world that an individual with hearing impairment is exposed to and how our intervention strategy must be changed depending on this.

RESULTS: The results obtained indicated that values of the psychophysical measures, DLF and Q10, were better among the Ms group. Statistically significant differences were seen when measurements were done at 1 KHz and 4 KHz. SOAEs were recorded in a higher number of Ms than NMs. Musical experience had a moderate positive correlation with PTC Q10 values at both 1 and 4 kHz, but not DLF values. CONCLUSION: This study indicates that musical experience enhances peripheral filtering, and thereby betters cochlear frequency selectivity in Ms.

Hearing aid is one among the rehabilitative option available to them. Even with advent in hearing aid technology, adequate benefit for hearing loss is a colossal challenge. It was hypothesized that channel free hearing aid improves the speech perception in presence of noise. Aim & Objective: To document consonant identification scores (CIS) and sequential transfer of information from multichannel and channel free hearing aids, in noise. Materials and Methods: Fourteen participants having bilateral sloping SNHL were included. Each participant was presented 21 syllables in unaided and aided conditions (4 channels, 12 channels, and channel free hearing aids) at quite, +10 dBSNR and 0dBSNR, to determine CIS and sequential transfer of information. Results: It was observed that signal-processing strategies did not significantly affect consonant identification at q...

Method: Pure tone audiometry, Single probe tone frequency tympanometry, MFT, MCT, Reflexometry and Bone Conduction Auditory brainstem response (BC-ABR) were carried out. Result and conclusion: The results of Pure-tone audiometry test indicated Normal hearing sensitivity in left ear and a Profound mixed hearing loss in right ear. The single probe tone tympanometry revealed an „As‟ type and an „A‟ type tympanogram in the right and left ear respectively. MFT revealed a mass dominated pathology in the right ear and a normal resonance in the left ear which in turn...

The single probe tone tympanometry revealed an "As" type and an "A" type tympanogram in the right and left ear respectively. MFT revealed a mass dominated pathology in the right ear and a normal resonance in the left ear which in turn correlated with the results of MCT. The threshold of right BC-ABR was obtained at 40dBnHL, which indicated cochlear hearing to be affected to a smaller degree as to be expected in advanced CSOM conditions. Compilation of results of test battery assists the Audiologist to draw the attention of the treating ENT specialist towards appropriate diagnosis, designing a suitable intervention plan, effective counselling and appropriate referrals.
