Audiogram: An audiogram is a graph which audiologist use to record results using symbols to depict the threshold for each ear as a function of frequency and intensity. How is hereditary hearing loss diagnosed?Physiologic testing includes:Auditory brainstem response testing (ABR, also known as BAER, BSER). Audiometry: Behavioral testing and pure tone audiometry Behavorial testing includes behavioral observation audiometry (BOA) and visual reinforcement audiometry. Audioprofile records several audiograms from one person at different times, but may include different members of the same family. Nonsyndromic hearing loss: Is associated with abnormalities of the middle ear and inner ear.
I shadowed my supervisor while she performed audios on different patients and I have gained valuable and useful skills during my observations.
It is known as the most common type of hearing loss and more than 90% of people who are hard of hearing have sensorineural hearing loss.
A person who suffers from a mixed hearing loss usually has strengths and weaknesses in their hearing.
Air conduction: Is the course of sounds that are conducted to the inner ear by way of the outer and middle ear.
The reason to do this is to prevent sound from the side being tested from going over to the good side. Our genes contain DNA (deoxyribose nucleic acid), a double helix of coded strands that contain information about our ancestors.


Comparing numerous audiograms, the age-related progression of hearing loss can be viewed within these families. Determining if hearing loss is hereditary may require genetic testing of all family members, as well as viewing medical histories if direct physical examination can not be performed.
I developed a variety of insights on the different degrees and types of hearing losses, differences between air and bone conduction, and the symbols used on an audiogram. As for the third diagram, I explained what an audiogram is and created a mapping key that is used when performing audio evaluations on a patient.
Someone that has that same hearing for air and bone conduction usually has normal hearing or sensorineural hearing loss. Conductive hearing loss can often be medically treated, and in many cases, hearing can be restored. This type of hearing loss results from a conductive and sensorineural hearing loss mixed together. Someone who has poorer hearing by air than bone eventually has conductive or mixed hearing loss. For individuals with permanent conductive hearing loss treatment such as hearing aids or bone-conduction hearing aids may be a feasible treatment option. Once they become damaged they are unable to convert sound vibrations into electrical signals required by the auditory nerve. With this degree of hearing loss the person appears to be able to hear soft sounds, can hear a normal conversation in a quiet room, has difficulty in a noisy environment, and cannot hear whispered conversation or speech from a distance. During audiogram evaluations the patient wears either headphones or inserts depending on the size of their ear canal for better results. When testing the hearing by bone, patients wear headphones positioned on the temple and cheek.


Having a family history of hearing loss or deafness puts everyone down the line at risk for this condition.
The electromechanical transducer, which converts electric signals into mechanical vibrations and sends sound to the inner ear through the cranial bones.
This is called hereditary hearing loss.Hearing loss can be described as the inability to hear sounds in our environment.
A person who suffers from this type of hearing loss typically states that they can hear people speak, but not understand what they are saying. A patient with this degree of hearing loss has difficulty hearing a normal conversation in a quiet room, and they must use lip-reading or amplification to comprehend most words. There are four types of hearing loss, which are conductive, sensorineural, mixed, and central. A moderate-severe hearing loss ranges from 55-90 dB HL and a person who suffers from this hearing loss cannot hear a conversation without being spoken loud enough into the ear by the speaker. These hearing loss types can be syndromic or nonsyndromic, and can happen before language development (prelingual) or after language development (post lingual).An important factor is determining if hearing loss is before birth (congenital) or after birth (acquired). A patient who has a profound hearing loss ranges from 90+ dB HL, cannot understand speech even if their being yelled at, and they can only hear very loud sounds. It's severity and location must also be diagnosed in order for the correct treatment to be administered for relief of symptoms to occur.The severity of hearing loss is measured in decibels.
