Causes of Hearing loss in Adult 1. Gradual (as in aging); 2. Sudden (as in viral infection, meningitis etc.); 3. Fluctuating (as in Meniere’s Disease)
Hearing loss is measured in decibel (dB). This number represents the softest level one can hear. In general, people with normal hearing (-10 to 25 dB) can hear most speech sounds in quiet and comfortable listening situations. If one can only hear sounds when they are at 30 dB or more, he or she may have a hearing loss. The levels of hearing loss are generally classified as mild, moderate, moderately-severe, severe, and profound.
Please check below different levels and
symptoms of hearing loss:
Mild hearing loss (26-40 dB) : can hear reasonably well in one-on-one conversation but may miss some words or speech sounds when speech is too soft or when there is background noise present
Moderate hearing loss (41-55 dB) : have difficulties to hear soft speech, can only hear about 50% of daily conversations
Moderately severe hearing loss (56-70 dB) : miss a lot of speech sounds and telephone conversation, have difficulty following speech without a hearing aid
Severe hearing loss (71-90 dB) : miss the vast majority of conversational speech and the use of telephones will be very difficult, need hearing aids to perceive speech sounds almost all of the time
Profound hearing loss (91 dB+) : cannot hear speech sounds even if they are very loud, need hearing aids or cochlear implants to perceive speech sounds, rely mainly on lip-reading and/or sign language
If you have the above symptoms, please contact us for an appointment of Free hearing test.
There are three types of hearing loss:
Conductive, Sensorineural and Mixed
Conductive hearing loss
Conductive hearing loss: caused by problems in the outer and/or middle ear, which dampen sounds getting through to the inner ear. The common causes include a build-up of earwax in the canal, eardrum perforation, fluid in the middle ear, and damaged or defective middle ear bones (ossicles).
Treatment: Hearing test(s) would be advised to confirm the type and level of hearing loss, and clients should consult doctor and/or specialists for further action; generally it can be alleviated by medications or surgery. Yet, for some cases hearing aid might be a better option.
Sensorineural hearing loss
Sensorineural hearing loss: caused by damage or malfunction of the inner ear and/or the auditory nerve. The common causes include aging, viral infection, Meniere’s Disease, head injury, ototoxic drugs, or prolonged noise exposure.
Treatment: Hearing test(s) would be advised to confirm the level of hearing loss, and then
consult hearing specialists for hearing aids fitting; most cases cannot be alleviated by medications or surgery. Hearing aids could be very helpful. People with severe to profound impairment can consider having cochlear implants.
Mixed hearing loss:
Mixed hearing loss: caused by a combination of problems in the middle and the inner ear, i.e., having both conductive hearing loss and sensorineural hearing loss at the same time and in the same ear or ears.
Treatment: maybe alleviated by medications or surgery, whether need to wear hearing aid or not depends on the severity of your hearing loss after treatment.

Naturally the earwax moves slowly out of your ear canal. Using cotton buds can push the earwax deeper into the ear canal. It is advised to see an ENT specialist for earwax removal if you feel you have a problem with earwax.
It is suggested to consult an ENT specialist if such problem lasts for a long period of time.
It is important to understand that tinnitus is a symptom rather than an illness, so the problem of tinnitus can only be alleviated.
In a hearing aid company, a hearing test will be done at the beginning, then the hearing aid is set according to the hearing level. More importantly, lifelong fine-tuning is offered; while if you buy an OTC hearing aid, that hearing aid is not customized to the hearing level and no after-sales service is provided .
For a first-time hearing aid user, he/she has not been hearing some background sounds for various periods of time owing to the hearing loss, so when putting on the hearing aid, the the background sounds being amplified may sound too loud at the beginning . When the user gets used to the hearing aid usage, he/she may feel better. Additionally with the advancement of noise reduction technology, hearing aid user shall have a much comfortable experience.
When you are sleeping with earphones every night, your ears will be constantly stimulated by music, so after a long period of time, the hearing may be affected eventually.
Sound or noise has two characteristics: Frequency (i.e. pitch) and Loudness
Sound is the quickly varying pressure wave induced by particle vibration through a medium (air, liquid or solid). The number of pressure variations per second is known as frequency of sound, measured in Hertz (Hz).
The higher the frequency i.e, the more cycles of vibration per second, the higher the pitch. On the other hand, the lower the frequency, i.e., the fewer cycles of vibration per seconder, the lower the pitch would be. The audible frequency range of human ear is from 20 to 200,000 Hz while the major frequencies for speech lies between 500 –4,000 Hz.
Loudness of sound is determined by the degree of particle vibration. A loud sound usually has a larger pressure variation while a weak one has smaller pressure variation. A simpler way is to measure in decibel (dB). The softest sound a normal human ear can detect i s known as the Threshold of Hearing, which uses the hearing threshold as 0 dB.
