People with moderate loss know they have hearing loss and it interferes with normal day to day activities if not corrected by wearing hearing aids. As shown in the audiogram to the right most of the Xs and Os indicate normal hearing until, in the higher frequencies on the right side of the chart, the symbols fall to reflect mild high frequency loss. An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies.
The pitches shown on the audiogram are those most important for hearing and understanding conversation. If air conduction testing shows a hearing loss, another device called a bone vibrator is placed behind the ear to send sounds directly to the inner ear. When something stops sounds from moving through the eardrum and middle ear, bone conduction hearing levels will be better than air conduction levels. Kemampuan ini berkembang seiring dengan perkembangan otak kita secara umum dan perkembangan indera kita lainnya, terutama penglihatan. Kita mencapai puncak dalam kemampuan mendengar dan menganalisis suara di awal usia dua puluhan. Dalam hal pengolahan suara, manusia mampu memproses berbagai macam frekuensi yang berbeda serta intensitas.
Kita dapat memproses dari frekuensi 20Hz yang sangat rendah, kedalaman suara sampai 20.000Hz yang sangat melengking dan tipis. Sebagai tambahan untuk membedakan frekuensi, telinga manusia juga mampu untuk memproses berbagai macam kebisingan suara, mulai dari suara yang sangat lembut di bawah 0 dB sampai sekitar 120 dB yang sangat keras dan dapat menyebabkan kita merasa nyeri.
Sistem pusat pendengaran di otak kita dirancang untuk menerima dan bekerja dengan beragam perbedaan dan perbedaan kecil di kebisingan dan nada.
Namun kita tidak menggunakan sebagian besar kemampuan ini secara sadar, baik itu mendengarkan musik atau percakapan. In principal the function of peripheral hearing is to convert sounds (air pressure differences) into electrical signals which the brain can interpret. The surface difference of the ear and the ear canal entrance causes the sound to get amplified.
The cochlea is central to our hearing, converting mechanical energy into electrical stimulation. The louder a sound is, the stronger the wave in the liquid will be and the more haircells ina certain area will be stimulated. Central Hearing is the brain’s ability to find meaning in the electrical stimuli it receives from the cochlea. These patterns are comprised of the relation between different pitches and loudness of each component of sound. Additional information is provided by differentiating and measuring minute time and frequency pattern differences from sounds arriving from different sides.
Hearing loss is the brain’s inability to assign meaning to electrical stimuli (it receives from peripheral hearing, the cochlea). Central loss indicates that the auditory areas of the brain, despite receiving adequate electrical stimuli from the cochlea cannot derive adequate meaning from it, especially in the presence of background noise or in challenging acoustic environments. In short, peripheral hearing loss is a physical problem, with one or several of the structures not working properly or missing, while central hearing loss is an absence, reduction or loss of ability. Sensory neural loss means the impairment in the sensory part, the cochlear and a loss of central (neural) ability to process stimuli from the cochlea. Mixed loss is a combination of sensory neural loss with peripheral conductive components or vice versa. Depending on which part of the auditory chain is impaired, signs and symptoms differ greatly. Conductive loss means that sounds or mechanical energyis not accurately conveyed to theliquid in the cochlea. Describes the brain’s inability to derive meaning from the electrical stimuli coming from the cochlea. Sensory neural is the most common form of hearing loss, and describes a combination of sensory and central loss.
Flat loss means that there is less than 10 dB difference from one frequency to another and less than 20 dB overall difference.


Sloping hearing loss means that hearing in the low frequencies is better than hearing in the high frequencies. Reverse sloping loss means that hearing in the high frequencies is better than in the low frequencies.
Hearing loss degree is calculated using the average threshold at 500Hz, 1000Hz and 2000 Hz. Whereas sever and profound losses are obviously to be addressed the importance of hearing treatment for mild hearing loss is often forgotten. Sudden loss of hearing may have it's cause in medical conditions, which require the immediate attention of a physician. Signs of hearing loss depend on the location of the problem and vary from simply not hearing loud enough to not understanding spokenlanguage even if it's loud enough. Accordingly hearing treatment needs to be fully customized depending on the sign of the hearing problems and lifestyle requirement of the individual.
Hearing problems might require a medical intervention, some electronic devices to amplify and modify the sound or training and re-training the auditory system.
Toprevent hearing loss is very important as many hearing problems could be easily avoided in the first place by adequatelyprotecting ones hearing.

Mild flat loss sufferers tend to listen to the TV or radio at higher volume than others do, finding that it is relaxing to have sounds turned up enough so they aren't straining to hear. The high frequency portion of the group of sounds that make up a word may be inaudible to people with high frequency loss. High frequency hearing loss, as shown in the audiogram above, has benefited from vast improvements in hearing aid technology recently.
A good physical fit is critical, hearing aids must fit very snugly to hold the sound in the ear canal but not so tight that it makes the ear or ear canal sore.


A child with this hearing loss may only hear very loud speech or loud environmental sounds, such as a fire truck siren or a door slamming. A child with this hearing loss will have difficulty hearing regular speech, even at close distances. A child with this hearing loss will have trouble hearing and understanding soft speech, speech from a distance or speech in a background of noise. Disini kami akan lebih sedikit menjelaskan mengenai bagian fisik dan lebih berfokus pada fisiloginya, yaitu menjelaskan bagaimana proses mendengar. Saat kita dilahirkan kita memberi asupan otak kita dengan informasi pendengaran yang membangun memori suara bermakna yang membantu kita untuk merasakan keajaiban pendengaran.
Sejak saat itu, umumnya, kemampuan pendengaran kita secara bertahap akan menurun secara perifer juga pusat. Telinga manusia sangat sensitif sehingga dapat membedakan suara, bahkan perbedaan 1dB sekalipun! Musik yang sering kita dengar hanya menggunakan rentang frekuensi dari sekitar 50 Hz sampai sekitar 15,000 Hz dan di tingkat kenyamanan pendengaran, memliki rentang intensitas dari 20 dB sampai sekitar 100 dB. Pendengaran perifer meliputi segala yang dilakukan telinga kita untuk memproses suara; Pendengaran sentral mengacu pada pusat pendengaran di otak kita yang menganalisis sinyal yang datang dari telinga dan mengartikannya. As the ears are forward facing and on each side of the head, sounds from the front are better received than the rear (Loudness difference) and reaches one ear before the other (time difference). In particular, sound in the 2-4000 Hz range gets accentuates, which is very important for speech understanding. These haircells are connected to strands of the hearing nerve which conduct the electrical signal to the brain. Depending on the frequency of these waves, hair cells in a certain area of the cochlea will respond by producing electricity. Peripheral means that the system which normally conducts sound efficiently and accurately through the ear to the brain is malfunctioned. The ear (auricle), the ear canal, the eardrum or the middle ear structure are all part of the conductive structure of the ear which converts air pressure differences to mechanical energy. Any problems in this area results not only in loss of loudness but also causes distortions and degrades signal quality. Unattended mild Hearing loss will affect central auditory processing and develop in a central problem before long. Central loss means the brain’s ability to assign meaning to electrical information is being reduced.
Other factors such as infections, toxic agents and accidents may also contribute to someone getting a hearing loss.
It may also be caused by accidents and traumas,especially to the eardrum, middle ear structures,tissue hardening or any abnormalbone growth. The softest sound an individual can hear is being recorded as the hearing threshold at that particular frequency. Traditionally High Frequency Loss has been one of the hardest to attain satisfactory improvement in hearing with hearing aids. Symptoms of high frequency loss are: not being able to understand speech except in quite environments, having trouble hearing TV and movies, or not being able to keep pace in conversations held in places with excessive noise such as busy restaurants or social gatherings.
Typically a conductive loss does not degrade the signal quality but results only in reduced intensity. It is then repeated at a number of different frequencies before being connected with a line. It's design reduced feedback and used an open earmold, overcoming the two major hurdles of high frequency loss - occlusion and feedback.
Since then, most of the other hearing aid manufactures have followed in Resounds footsteps and released similar technologies.
