Here, since the left curve is higher on the chart, the left ear actually can hear better, even though the right ear is considered normal. If your Hearing Curves are within the shaded “Normal Hearing Area” then you hear all tones very well! The sample printout shows the four tested areas from the Hearing Booth and shows a 0% loss in each ear at all checked areas. It is very common for people to have a high pitch hearing loss, and this type of loss is very rewarding to correct. Because the red line is higher on the chart, the right ear tested better than the left although both sides need hearing correction to hear clearly.
For this reason, people with a high pitch loss oftentimes complain that people mumble or speak incorrectly.
If you register with the Hearing Curve, you’ll find the Speech Banana chart relative to your Hearing Booth results. Depending on severity, may miss hearing high pitches noises like a phone ring, microwave or wrist watch beep if not close enough to it. At times, it may be easy to predict or guess to fill in the gaps when they don’t hear all the information, based on knowledge of the speaker, the context, and the topic of conversation.
Here there is considerable hearing loss in each ear, although the left ear is a bit better.
The left ear here is a bit better than the right ear, but both sides need hearing correction.

Our sense of hearing is a product of an amazingly complex system that converts sound from air pressure to mechanical vibration to neural impulses. The purpose of this article is to help our clients understand the a€?audiograma€?, which is the graph that we use to chart the severity and the configuration of hearing loss. When we consider how we hear, we think about the amazing complex function of the outer, middle and inner ear.
Otocacoustic Emissions (OAEs) are sounds that are naturally produced by the activity of the inner ear. Our friendly staff will be happy to discuss your particular needs and schedule an appointment with one of our registered audiologists. Smits and colleagues [64] demonstrated that over 50% of those referred to medical or other professional hearing healthcare in The Netherlands were compliant in following this advice. This article is intended to outline the basic physiology and function of our hearing system from the outer ear to the inner ear. Often people wonder if it is possible to describe hearing loss in terms of a a€?percentage of lossa€™. However, the pathway that the auditory signal takes through the brainstem and up into the brain is even more complex and important for the processing of speech.
OAEs are present when there are healthy cells (called outer hair cells) in the hearing part of the inner ear called the cochlea. On the other hand, Meyer and colleagues [63] showed that only 36% of the 193 individuals who failed the Telscreen in Australia went on to receive medical or other professional support.
Some people have very keen hearing (meaning their Hearing Curves are high up on the Hearing Curves chart). Hearing aids and associated rehabilitation programs have been shown to minimise such impacts. It is not clear whether such differences in health-seeking behaviour are explained by cultural, social, or economic factors.6.

The US National Council on Aging survey of 2069 hearing-impaired individuals and 1710 of family and friends demonstrated that hearing aid use is associated with lesser degrees of anger and frustration reported by family members [12]. Speech-in-Noise TestsAnother hearing screening program is the use of an automated face-to-face monosyllabic speech-in-noise test which aims to evaluate hearing disability in adults. Often, this is after the loss having led to multiple negative consequences including effects on employment, depressive symptoms, and increased risk of mortality. The speech understanding in noise (SUN) test was developed by Paglialonga and colleagues [66, 67] and has been evaluated in multiple nonclinical sites with varying levels of ambient noise showing good sensitivity up to 65 dBA.
In contrast, the use of hearing aids is associated with reduced depression, longer life expectancy, and retention in the workplace. The SUN test presents monosyllabic vowel-consonant-vowel sounds in a 3-alternative forced-choice paradigm. Despite this, several studies indicate high levels of unmet need for hearing health services in older adults and poor use of prescribed hearing aids, often leading to their abandonment.
The response is provided through a touch screen, thereby avoiding tester scoring errors, and takes approximately 2 minutes to evaluate both ears. In Australia, the largest component of financial cost of hearing loss (excluding the loss of well-being) is due to lost workplace productivity. Good associations were found between pure-tone audiometry and referral on the SUN test [66] which indicates the benefit of this test as a screening test for adult hearing loss.7. Nonetheless, the Australian public health system does not have an effective and sustainable hearing screening strategy to tackle the problem of poor detection of adult-onset hearing loss.
ConclusionsGiven the ageing demographic and increasing average life span in Western countries, chronic hearing loss is projected to increase.
While milder forms of hearing loss may be less correlated with hearing disability, Dillon [10] showed that more significant losses do show higher levels of benefit. A renewed focus on targeting the provision of hearing rehabilitation to people with self-perceived hearing disability, rather than those with only measured hearing loss, may lead to better long-term retention and use of aids. This paper reviews the current literature, including population-based data from the Blue Mountains Hearing Study, and suggests different models for early detection of adult-onset hearing loss.1.


IntroductionAdult-onset hearing loss is a highly prevalent yet relatively underrecognised health problem in the older adult Australian population [1, 2]. Because hearing loss is often progressive and gradual in its onset in most individuals, it is typically diagnosed and managed several years after its onset, often only after having led to multiple negative consequences including effects on employment, poor quality of life, social isolation, depressive symptoms, increased mortality risk, and reduced independence [3–9].
It is one of the leading causes of burden of disease prior to older age, for ages 45–64 years, in men and women [9]. Greendale, “Hearing loss in community-dwelling older persons: national prevalence data and identification using simple questions,” Journal of the American Geriatrics Society, vol. Therefore there is a need to better understand the barriers that may exist to help seek an effective remediation for hearing loss in this population.Hearing loss is a chronic problem and, contrary to current community perception and funding models of hearing services, hearing aids are typically a part of a rehabilitation program rather than provide a single and simple restorative solution to hearing loss [12]. However, similar low rates of hearing service uptake and device use have been observed in the Australian Federal Government Office of Hearing Services program [10], where hearing services are largely provided free of charge to eligible older adults.
As such, hearing loss needs to be effectively managed under a biopsychosocial model of care [13], following the framework for intervention and treatment of the International Classification of Functioning Disability, and Health model [14].
Therefore, we assume that under use of fitted aids by older adults in Australia may suggest either poor targeting of individuals with hearing loss or fitting at too late a stage for derived benefit.
This framework not only considers the impairment per se, but also the impact that it has on the individual in terms of activity limitations (such as inability to perceive speech in noisy environments) and participation restrictions (such as the ability to fully participate in communication and conversational activities) [15]. Substantial delays in accessing hearing services may impact effective hearing aid use because advancing age is associated with poorer auditory and cognitive processing, physical dexterity, and learning abilities making it more challenging to perceive sounds in competing noise environments, position a hearing aid in the ear, and to learn how to use new technology [38–41]. Nonetheless, hearing aid use is a measurable quantity and, therefore, the majority of studies that have evaluated functional and quality-of-life outcomes of rehabilitation programs for individuals with hearing loss have used this as a marker. Additionally, there is an increased likelihood of other health problems coexisting so that the management of hearing loss may be considered less of a priority and prove to be burdensome.
Multiple studies have identified that rehabilitation interventions can effectively address many of the difficulties associated with impaired hearing [16–20]. Importantly, evidence shows that the later hearing rehabilitation occurs in the course of hearing loss, the less likely older adults are to continue to use and derive benefit from hearing aids [21]. GP Hearing Screening StrategiesThere remains a large proportion of hearing-impaired adults who would benefit from hearing aids but who decide not to seek help [21]. Despite this, several studies [22, 23] indicate high levels of unmet need for hearing health services and poor use of prescribed hearing aids. Similar studies of GPs undertaken in UK identified that the chance of referral to hearing services for older adults who reported hearing loss was only about 50% [42]. Other reasons include an underestimation of the negative impacts of hearing impairment on overall health by general practitioners (GPs) and older adults, leading to poor referral to appropriate medical and allied health practitioners, such as ear, nose, and throat specialists and audiologists [24]. Screening and intervention programmes have been recommended to improve this situation [21, 43]. To date, the Australian public health system does not have an effective and sustainable hearing loss screening strategy for late-onset hearing loss in adults to manage this problem. Screening programs are not systematically implemented throughout the Australian population, their success at meeting the needs of the target population is not assured, and they have no automatic link to action if the need for action is detected [44]. This paper aims to review the current pathway of detection, referral, and management of late-onset adult hearing loss in Australia and to identify an alternative, more effective pathway for the future. Audiograms conducted by trained audiologists in soundproof booths, are currently used to diagnose hearing impairment and largely determine whether or not an individual is offered hearing rehabilitation. Mitchell, “Hearing impairment and health-related quality of life: the blue mountains hearing study,” Ear and Hearing, vol.
Particularly for late-onset hearing loss, it provides little information about effects of hearing loss on everyday functioning [45, 46].
Of these, 870 participants without hearing loss and 439 with hearing loss were reexamined during 2002–2004. It is important to note that while hearing impairment is extremely common in older adults, not all are significantly disturbed by this. The BMHS findings collectively show that severe hearing disability is strongly associated with measured hearing loss, poorer QOL, and probable depression.
This suggests that identifying hearing-related activity limitations and participation restrictions could potentially be effective in identifying persons more likely to have suffered an important impact from their hearing impairment and, thus, would be most likely to benefit most from using hearing aids. In fact, Dillon [10] showed that the benefits reported by individuals with hearing aids appear to be only weakly correlated with hearing loss, particularly for mild-moderate losses. This may in part explain why at least 20% of individuals fitted with hearing aids do not wear them. On the other hand, benefits are actually more highly correlated with initial motivation and perceived listening difficulty [10, 47, 48].
Thus, greater engagement by GPs in hearing health could potentially be a cost-saving strategy, as GPs are ideally placed to better motivate and identify older people with hearing loss disability, that is, those likely to benefit the most from a hearing aid, thereby improving the targeting of hearing-impaired patients for rehabilitation.There exists a need for a readily accessible screening test assessing hearing disability which could more accurately identify rehabilitation need, rather than just measurement of hearing loss. Validated, self-administered questionnaires about hearing disability have been shown to detect functional hearing impairment accurately and, so, have been recommended as potential screening tools [49–52].
In particular, it has been suggested that primary care services could cost-effectively be used to identify hearing disability using targeted questions, possibly alongside other screening interventions [21, 43].
Previous work through UK GP-based case finding, which targeted people in the 50–65-year age group, showed that effective hearing aid use can be at least tripled [30, 54]. One study assessed the patient’s take-up of hearing disability screening and the subsequent take-up of hearing aids as an intervention for hearing disability. Substantial benefits were reported in hearing aid benefit outcome inventories and moderate benefits in health utilities index and quality-of-life scores from amplification for this target group [21]. Trabucchi, “Sensory impairments and mortality in an elderly community population: a six-year follow-up study,” Age and Ageing, vol. The authors concluded that simple questionnaires are effective in detecting hearing disability in older adults and that this intervention was acceptable by many of those reporting significant hearing difficulties.
Given the pivotal role of the GP in the early identification and management of chronic health problems, at least in Australia, the implementation of a GP-based hearing screening program for adults >50 years of age would be beneficial in addressing this problem. Further, with the inadequacies of the medical model in the treatment of chronic health conditions and the move towards a model of patient-centred care, GPs are effectively placed to assist with the minimisation of the stigma associated with hearing loss and enhancing patient self-motivation to manage this [55].
However, several such studies identified that the knowledge and attitudes of GPs can be a major barrier to effective intervention within this process [38].
This could be achieved by sensitising GPs to recognise at-risk individuals and providing targeted questions to identify hearing loss disability.


Ventry, “Hearing impairment and social isolation in the elderly,” Journal of Speech and Hearing Research, vol.
We have identified an important role of GPs in the process of targeting individuals with late-onset hearing loss and referral; however, the challenge that remains is how to effectively increase GPs knowledge and practice behaviour in this area.
Possibly the most obvious method is through development of a continuing medical education (CME) program that targets the impacts of hearing loss and remediation and provides a reliable method of hearing screening in adults. The evidence for good outcomes of CMEs measured by factors including increased knowledge and skills as well as altered attitudes and practice behaviours is varied and possibly depends partly on the learners and learning context [59].
A review of the literature has identified that while the quality of evidence is not high, generally CME provides a strategy that increases knowledge and may elicit a change in practice behaviour [60].
However, in a meta-analysis of the CME literature, Forsetlund and colleagues [61] report that education meetings are likely to only have a moderate effect on professional practice and a smaller improvement on patient outcomes. Therefore it is possible that both educational meetings and Internet-based programs will have only a moderate impact in enhancing referrals to hearing healthcare providers. In addition, this presumably has a broader reach than GP screening because of the program’s accessibility to individuals in rural and remote areas where worldwide shortages of healthcare professionals and services exist [65]. Further, it provides information about the individual’s hearing to the significant proportion of individuals who were not intending to see a GP or hearing healthcare provider (as shown in [64]). Smits and colleagues [62, 64] developed the first telephone screening test which was introduced into The Netherlands in 2003 as the National Hearing Test. Karpa et al., “Hearing loss impacts on the use of community and informal supports,” Age and Ageing, vol. The noise was amplitude modulated by a 20 Hz sinusoid and had gaps in the frequency spectrum to increase the sensitivity of this test to identify sensorineural hearing losses (described in [63]).
