Mdm Vani is brought in by her daughter to get her ears checked. She is 80 years old and her daughter claims that her mother has had hearing loss for a few years now. Because she lives alone in a 3-room HDB flat, she is in need of hearing aids as she has trouble using electronic devices daily and family members complain that Mdm Vani cannot hear them whenever they call her on her cellphone. This is the audiogram of Mdm Vani’s ears after conduction of the hearing test. Hearing loss Classification (Air Conduction):
From 250-100Hz, the thresholds of Mdm Vani’s ears range from -5 up to 25dB. This indicates that her ears are functioning normally at these frequencies. However, from 2000-8000Hz, the threshold ranges drop drastically and range from 35 to 65dB in the right ear, showing a sloping mild to moderately severe hearing loss. In the left ear, it has better results, ranging from 25 to 50dB, indicating mild to moderate hearing loss, proving that the better ear is the left.
Bone Conduction testing:
Bone conduction (BC) was required for Mdm Vani because the air conduction thresholds are worse than 25dB at the frequencies of 2000, 3000 and 4000. A bone conductor is used to send sound directly to the inner ear by vibrating the bone behind the ear. It is a test of the inner ear only as it bypasses the outer and …show more content…
When compared to the Articulation Index (AI) graph, Mdm Vani could understand about 78% of the words that are being said. This shows that at least Mdm Vani could not understand 22% of the words when she is communicating with her family members over the phone. The hearing loss also begins from the 1000 Hz mark in the worse ear. Mdm Vani could hear more of speech but is handicapped during noisy situations. Due to the loud noises from the TV, it could have affected her ability to hear properly as well as listen to the phone rings and words being said over the
