    have extremely poor to no measureable hearing in the high frequency ranges In simplified form SoundRecover acts to take those frequencies where no measurable hearing is found and shifts them to lower frequency ranges where the hearing loss is less severe By re creating so to speak some of those high frequency sounds this may help to restore clarity and improve intelligibility of speech sounds SoundRecover is simply activated in the programming software by your audiologist Cros and Bicros Hearing Aids Although it s more common for people to have hearing loss in both of their ears some people have normal or near normal hearing in one ear with no useable hearing in the other ear This means that the hearing loss is so severe in the poor ear that a hearing aid would not help There are several limitations to only having hearing in one ear such as losing the ability to localize where sounds are coming from not hearing someone speaking to you if they are on the poorer side and having to constantly turn your head with the better ear toward the sound source The CROS BICROS hearing system helps to resolve these issues as the device on the poor ear side picks up sounds and transmits them to the better hearing ear device Although this device does not restore natural hearing having awareness of sound on the poor ear side will help to open up possibilities to once again participate in situations that were previously overwhelming when relying only on one ear hearing Additionally sound awareness on the poorer side will assist with sound localization the ability to determine from which direction sound is coming Remote Controls Depending upon the size and style of your hearing aid you may or may not have access to features such as a volume control or a program change button for optimal hearing in a variety of listening situations Additionally some individuals may want to be discreet with their hearing aids wanting access to these features without having to bring their hands up to their ears while others have dexterity issues making it difficult to find the volume or program controls Regardless of the reason most hearing aids these days have the option of a remote control device allowing the individual to make volume changes to suit the multiple environments that may be encountered throughout the day Remote controls also allow for changing to customized programs such as a program to help in the presence of background noise for telephone use and for listening to music to name a few Some remote controls have an automatic reset button so if you are unsure what volume setting you are at or which program you are in you simply press the reset button and the hearing aids return to their originally programmed settings Depending upon the hearing aid some remote controls also act as a Bluetooth interface for connectivity to Bluetooth enabled devices such as a cellular phone computer or iPod Consult

    first one third of the canal is made of cartilage while the inner two thirds is made up of bone The earwax glands are located along the walls of the canal and serve to lubricate the canals and protect our eardrum from dirt debris and insects The ear canal also causes a resonance that amplifies higher pitch sounds travelling to the eardrum helping us hear many softer speech sounds The middle ear begins at the tympanic membrane more commonly known as the eardrum which is about 8 10 mm in diameter and made up of a thin layer of skin Sound vibrations are transferred from the eardrum to the three ossicles bones of the middle ear system the malleus incus and stapes These are the smallest bones in the human body Sound is amplified through the middle ear system because of the size difference between the eardrum and Click image to enlarge the end of the stapes bone and also from lever type action of the ossicles Air pressure in the middle ear is equalized by the Eustachian tube which is connected to the throat and opens when we yawn and swallow From the bones of the middle ear the mechanical back and forth movement of the stapes creates pressure waves that travel through the fluid of the hearing portion of the inner ear a snail shaped bone incased organ called the cochlea Here waves travel along the surface of a rigid membrane called the basilar membrane Higher pitch waves travel shorter distances and lower pitch waves travel longer distances This means the cochlea is arranged tonotopically it is tuned at all points to specific pitches It is here that receptor cells called hair cells transfer the sound waves into neural impulses Some of these hair cells send impulses to

    and as we go from left to right the frequency value gets higher and the tones are higherpitched The amount of hearing loss is depicted from top to bottom and is measured in decibels loudness Higher decibels are towards the bottom of the graph and they represent greater hearing loss We use circles to plot right ear Click graph to enlarge hearing loss and crosses to plot left ear hearing loss These marks represent how loud a tone must be for the person to hear it in a quiet environment in the sound booth We can draw a line between the circles and crosses to show how hearing loss can slope up or down at different pitches For example if someone has a hearing loss that is more severe for high pitch sounds then the lines on the graph will slope downward as it moves from left low tones to right high tones An individual may have hearing loss for all pitches or he she may have normal hearing for some tones and hearing loss for other tones Many hearing loss configurations are possible although some are more common than others It is valuable for a person with hearing loss to understand which pitches of sound are difficult to hear because it can help them understand how hearing speech and other important sounds will be affected In the graph below the pitch and loudness of different English sounds is shown The circles and crosses that are connected on this graph are an example of an audiogram In this example the speech sounds that are under louder than the left and right hearing levels will be hard by the individual but the speech sounds located above softer than the hearing levels indicated on the graph will not be heard by this

    sound develops early and continues to develop until approximately 10 years of age Children with auditory processing problems have great difficulty in school as they are unable to process instructions especially in background noise They often have difficulty with language and reading development Differentiating between APD and other childhood disorders such as attention deficit disorder language impairment reading disabilities learning disabilities reduced intellectual function and peripheral hearing loss is difficult A number of specialists are required to determine the true nature of a problem If a child you know is displaying the following symptoms they possibly have Auditory Processing Disorder APD 1 Frequently misunderstands oral instructions or questions 2 Delays in responding to oral instructions or questions 3 Says huh or what frequently 4 Frequently needs repetition of directions or information 5 Frequently requests repetition 6 Problems understanding in background noise 7 Is easily distracted by background noise 8 May have problems with phonics or discriminating speech sounds 9 May have poor expressive or receptive language 10 May have spelling reading and other academic problems As individuals age their hearing can decline but their auditory processing abilities can decrease as well Other medical conditions such as strokes tumours on the

    the ear OAEs can be measured by extremely sensitive microphones placed in the ear canal The benefits of OAE testing are Our measure of OAEs is sensitive enough to detect hair cell damage in the cochlea that indicates a mild hearing loss or even the probability of future hearing loss This is especially useful for detecting early signs of hearing loss for people who are concerned about a family history of hearing problems or for people who are concerned about hearing damage caused by loud noise e g musicians industrial workers hunters OAE measures can be used to monitor the effects of medications that are associated with hearing loss Changes in the health of outer hair cells may be detected before a significant hearing loss is caused by the medication OAEs are measured at many different frequencies tone pitches This provides the audiologist with a measure of outer hair cell function and potential hearing loss at specific areas of the inner ear Another important benefit of measuring OAEs is the fact that the client does not have to respond during testing It is completely automatic and all that is required is about 10 minutes in a relatively quiet room This
