Hearing is one of the most vital senses that helps us connect with the world. When hearing ability is reduced, it affects communication, relationships, and overall quality of life. Among the various degrees of hearing loss, moderately severe hearing loss is a significant stage that requires timely diagnosis and intervention.

Definition
Moderately severe hearing loss is a level of hearing impairment where the individual’s hearing thresholds range between 56 to 70 decibels (dB) on an audiogram. At this level, normal conversational sounds and many environmental noises become difficult to hear without amplification.
People with this degree of hearing loss may struggle to follow speech even in quiet environments, especially when the speaker is not facing them or when multiple people are talking.
Common Causes
Several factors can lead to moderately severe hearing loss, including:
-
Age-related hearing loss (Presbycusis)
-
Prolonged exposure to loud noise (occupational or recreational)
-
Ear infections or chronic middle ear problems
-
Ototoxic medications (certain antibiotics or chemotherapy drugs)
-
Genetic or hereditary factors
-
Sudden sensorineural hearing loss
-
Head injuries or trauma
Symptoms
People with moderately severe hearing loss may experience:
-
Difficulty understanding normal speech without a hearing aid
-
Asking others to repeat themselves frequently
-
Turning up the volume of TV or radio higher than normal
-
Trouble hearing in group conversations or noisy places
-
Misunderstanding words or sentences
-
Social withdrawal due to communication challenges
Diagnosis
An audiologist or ENT specialist diagnoses hearing loss using an audiometry test, which measures hearing sensitivity across different frequencies.
-
The test results are plotted on an audiogram, showing the degree and type of hearing loss.
-
Moderately severe hearing loss is identified when thresholds fall between 56–70 dB HL.
Treatment and Management Options
-
Hearing Aids:
Modern digital hearing aids are the most effective solution for this level of hearing loss. They amplify sounds clearly and comfortably, improving communication and confidence. -
Assistive Listening Devices (ALDs):
Devices like amplified telephones, TV streamers, and FM systems help in specific listening situations. -
Medical or Surgical Treatment:
If the hearing loss is due to an infection, fluid, or blockage, medical or surgical treatment may restore hearing partially or fully. -
Aural Rehabilitation and Counseling:
Speech reading training and communication strategies help individuals adapt better to their hearing condition.
Living with Moderately Severe Hearing Loss
With the right hearing aids and professional guidance, people with moderately severe hearing loss can lead a normal, active life. Early diagnosis and rehabilitation prevent further deterioration and enhance day-to-day communication.
Regular hearing check-ups, ear protection in noisy environments, and proper hearing aid maintenance are key to long-term hearing health.
