The UK Biobank offers cross-sectional epidemiological data collected on >500,000 individuals in the UK between 40 and 70 years of age. There is sufficient evidence to conclude that there is a connection between sensory decline and cognitive decline. In the current study, based on a large sample (N = 138,098) of people not using hearing aids from the much larger UK Biobank Resource (N > 500,000), we therefore focused on the effects of hearing loss and age on memory tasks that were not confounded by possible auditory perceptual degradation, or by attentional demands related to hearing difficulties, strictly testing the memory systems hypothesis. Testing the memory systems hypothesis, we used two types of memory tasks, tapping visuo-spatial working memory and visuo-spatial episodic long-term memory, respectively. The sample from the UK Biobank resource used in the present study is extremely large compared to that used in any other study in the literature on this topic. The study presented here is covered by a Research Tissue Bank approval obtained by UK Biobank from its governing Research Ethics Committee, as recommended by the National Research Ethics Service. The participants completed a functional hearing test in which they were presented with digit triplets in a steady state, speech-shaped noise (Smits et al., 2004) and had to enter (on a numberpad shown on the touchscreen) which three digits they had heard (forced choice).
For the memory measures, logarithmic transformation of the number of errors made in VSWM and the errors scores in PLTM were computed (for both measures: natural logarithm of x + 1) to counteract the skewed distribution of the raw scores. To be able to compare error rates on the dependent variables VSWM and PLTM in the ANOVAs, rather than in regression analyses with dummy coding of the interactions, the age and the hearing variables were divided into sub-groups. The Age by Hearing status distribution is shown in Table 1 of our N = 138,098 in our subsample. Table 2 shows the dichotomized fractions of men and people with an education other than University, College, A level, AS level in the Age × Hearing status groups.
We also decided to take a parametric approach to how to treat the logarithmic error scores for VSWM and PLTM. Figure 1 presents the mean error scores (ln(1 + x)) plotted as a function of age and hearing according to Dawes et al. Thus, PLTM seems to be more sensitive to functional hearing status and judging from Figure 1, the dominating difference is between the poor and the insufficient hearers. It has been estimated that around one in three people with learning disabilities may have a sensory impairment, rendering the condition far more common amongst this community than it is amongst the general population. With the advent of better Bluetooth technology, it has changed the way those with hearing loss and impairment deal and interact with the wider world. With connect-ability to the world’s most popular smartphones, the hearing aid has now reached the level of one to the most innovative wearable digital devices on the market. These products are changing the way people to listen to music, watch television or visit the cinema. In a recent interview with LiveScience magazine, Louise Levy, an audiologist in New York, said these "smart" hearing aids are giving people greater control over their environment.
Those with hearing loss have to interact with the outside world, but they often feel isolated.
With the aid of these new devices, users can connect wirelessly with smartphones, allowing them to control volumes without affecting others. They give you the ability to answer calls and listen to music directly to your hearing aids no matter where you are and what you’re doing. Beyond new Bluetooth products, there are other impairment aids that have been designed to help people enjoy common forms of entertainment.
Like the well-known Google Glass, the Access Glasses show closed caption information at the bottom of the user’s line of vision. With the expansion of virtual reality technology – thanks in part to Facebook’s recent purchase of VR pioneer Oculus Rift – those in applied gaming industry hope the technology can be used to make video games more accessible for those with hearing impairments as well. New innovative technology is wonderful, but audiologists and hearing impairment professionals are tasked with making this new technology useful and appealing to all generations.
All over the world, including studies by hearing charities in the UK, hearing loss by elderly patients often leads to feelings of isolation and may result in a decline in mental health or the onset of dementia. Don't forget to download our Hearing Advice Guide which offers guidance to people with hearing loss, ensuring that they get the hearing aid which is right for them. If you're worried you may have suffered some hearing loss, you shouldn't wait till your next routine doctor's visit. Instead you can inform you GP, who may carry out some preliminary tests at the surgery, or may refer you for specialist investigation.
Sensorineural hearing loss, caused by changes in the inner ear, is a more common cause of hearing loss in older people. This loss happens as the cochlea in the inner ear becomes less effective at picking up sound, especially high-pitched ones, often causing difficulty following conversation in a noisy environment.
Sensorineural hearing loss is assessed by audiometry: you listen through earphones to sounds of different frequencies and volumes, and the equipment records how loud a sound must be at any given frequency for you to be able to hear it. Hearing aids are battery-powered, designed to amplify sounds by means of a tiny microphone, amplifier and speaker.
Many different types of hearing aids are available on the NHS, including digital hearing aids.

Using the UK Biobank data, the aim of this study was to investigate the effects of functional hearing loss and hearing aid usage on visuospatial memory function.
At the beginning of the session, subjects were given instructions (written on the computer screen) stating that they were to touch a colored shape when prompted at the end of the session. In this way we can cast more light on the influential Baltes-Lindenberger common-cause hypothesis.
In the present study, we excluded participants who were born outside of the UK and the Republic of Ireland, as unknown language and cultural differences may significantly affect their cognitive abilities.
Among the UK population, 114,717 (25%) reported having general difficulty with hearing, 169,055 (37%) had difficulty hearing in noise, and 14,010 (3%) wore hearing aids.
In our sub-sample of 138,098, 89% (of 137,978) reported having eye-glasses and 88% (of 101,845) reported having no additional eye-problems. All test data used in this study were obtained through a self-administered program running of a computer with a touch screen that collected responses to questionnaires and tests on hearing in noise and cognition.
The speech reception threshold in noise (SRTn) was the SNR arrived at after 15 presentations, during which noise was adaptively changed after each presentation depending on whether the three digits were correctly identified or not.
We here describe the pairs matching and the prospective memory tests, as they are used for the short-term—long-term memory distinction relevant to this paper. Also, for the analyses of the VSWM and PLTM tasks, individuals with values above the 99th percentile on the six pairs matching tasks were excluded to build in a safeguard against outliers. Our aim was to have at least about 100 observations for each combination of age and hearing status. Table 1 also shows the defining criteria for the three hearing status groups: Normal, Insufficient, and Poor. These fractions do not vary substantially between sub-groups, but the means in the groups were statistically evaluated in our subsequent analyses (see below under Section Additional Analyses). Proportions of men (1st fraction in each cell of the table) and proportions of persons with an education other than University, College, A level, AS level (2nd fraction) in the Age by Hearing status groups. The basic issue is whether it can be justified to treat the scores as being on an interval scale, and reanalyze them with parametric tests, such as ANOVA, or whether the data only meet ordinal scale properties and should thus be subjected to non-parametric tests.
Mean error scores (ln(1 + x)) plotted as a function of age and hearing according to Dawes et al. F-tables for VSWM (upper panel) and PLTM (lower panel) by Hear and Age for the values given in Figure 1. To statistically corroborate this difference we conducted follow-up ANOVAs on the 12,157 insufficient hearers and compared them with the 1340 poor hearers.

It is clear that the positive effects of this technology can also be seen though the enjoyment of various forms of entertainment – previously shut off to those who can’t hear.
They may not be as exciting as new ways to track your walking or running, or as fancy as a new Apple watch, but these new hearing aids are changing the world around them for those with hearing problems.
Today, instead of listening in with headphones, users of these innovative Bluetooth hearing aids can connect directly to their smartphones, mp3 players, digital TVs, tablets and computers. They can have phone conversations directly through his or her hearing aid without needing to hold the phone against the ear. There is a common belief that for patients who aren't confident using various mobile technology, Bluetooth hearing aids may be daunting. Researchers, doctors and audiologists are hopeful that new technologies will help keep those negative effects of hearing loss away. A free hearing test is also available over the telephone from hearing charity the Royal National Institute for the Deaf. Many people find their hearing becomes less acute once they are past the age of 50, and the majority of over 70s has some degree of sensorineural hearing loss. However, many people, especially those experiencing an age-related decline in their hearing - can benefit from using a hearing aid. It is essential that they are properly fitted and adjusted to precisely match an individual's level of hearing loss. Ask your doctor for details of your nearest NHS Hearing Aid Centre or contact the RNID which has comprehensive information on all types of hearing aids. This selection of variables resulted in a sub-sample of 138,098 participants after discarding extreme values.
This effect occurs even when the hearing loss of the study sample was mild (25–30 dB). Two versions of the task were employed, an easy one with three pairs (which was considered to be a warm-up task), and a more difficult one with six pairs (loading highly on visuospatial memory).
Crucially, they were also informed that the prompt on the screen would say blue square, but as a prospective memory test, they should instead touch the orange circle. We also excluded participants whose data sets were incomplete across measures of hearing and cognition. In our sample of 138,098 persons, we had data for 130,206 on reported general difficulty with hearing, and 24% reported such difficulty.
Incomplete data sets were collected as it was possible for participants to be selective in which questionnaires and tests they responded to.

These SNR could vary between −12 and +8 dB, where a high and positive score indicated worse hearing. Data on reverse digit span were also available from the UK Biobank resource but were not used in the present study with its focus on visuo-spatial memory function. Participants were presented first with a round of three pairs of cards depicting different designs of objects and then, twice, with a round of six pairs of cards. With the functional hearing status variable already divided into three groups (Good, Insufficient, and Poor), as suggested by Dawes et al.
We concluded that an ANOVA approach is justified, but we will discuss the pros and cons of that at the end of the Results Section and also provide non-parametric analyses of our data to support the parametric statistical analyses.
The technology also lets users remotely control the volume of both hearing aids, the perfect feature when walking through busy environments or in crowded areas. These new products also can also be tracked via an electronic signal to avoid losing your aids. Recently, Sony Entertainment released their Access Glasses to give deaf and hearing impaired film lovers a way to watch with closed captions at the cinema. Increasingly, she's been pushing Bluetooth technology, but said it is easier for her to convince younger patients that "smart" hearing aids are the way to go.
Even once this adjustment has been made, many people find they must persevere for some time before the notice any real improvement in their hearing. A digit triplets functional hearing test was used to divide the participants into three groups: poor, insufficient and normal hearers. Another explanation is that the sensory loss actually causes the cognitive decline (called the sensory deprivation hypothesis), and a third alternative is that cognitive decline drives sensory loss (Baltes and Lindenberger, 1997). Thus, we opted for the six pair version in our analysis to maximise the demands on working memory.
Thus, by using the two visuospatial memory indices briefly described above, we were able to make a very conservative test of the hypothesis that functional hearing loss is more strongly related to episodic long-term memory decline than to short-term or working memory decline and that these declines are not caused by perceptual degradation or lack of attention resources. For hearing in noise, we had data for 134,673 persons and 34% reported difficulties with that. The ANOVAs were computed separately for VSWM and PLTM with Hear and Age as independent between-person factors. It was further reasoned that because speeded non-word repetition was intact even in the hearing-impaired groups, the actual perceptual processes were intact. With respect to hearing aid usage, 3751 persons (2.6%) in our sample reported wearing a hearing aid. There were no specific selection criteria applied to choosing the designs of the pictures other than that they should look reasonably distinct.
Then the Pairs matching test, the Fluid intelligence test and the Reaction time (Snap) test were performed.
As can be seen from Figure 1 and as confirmed by the ANOVAs (see Table 3) there are significant effects of both Hear and Age. Note that as the x-axis is the actual mean ages in the age-groups, the slopes of the lines between the age-groups are on a comparable scale.
The use of hearing aids showed a small positive effect for working memory performance for the poor hearers, but did not have any influence on episodic long-term memory. Thus, the results suggest that relative decline in a memory system is tightly connected specifically to hearing loss rather than to sensory decline in general. Thus, there were no systematic phonological or semantic relationships between the English lexical labels of the pairs of objects. If the participant touched any of the symbols it was highlighted by surrounding it in a yellow box. The Age effect is about equal in terms of F-values for the two memory tests, but the effect of Hear for PLTM appears to be stronger than it is for VSWM. Age also showed strong main effects for both memory tasks and interacted with gender and education for the long-term memory task. Broader theoretical implications based on a memory systems approach will be discussed and compared to theoretical alternatives. For those who only completed the test on one ear, it is assumed that this was the better ear, and this result is recorded. As a second step, we classified the participants on the basis of the criteria used by Dawes et al. If the participant touched the Blue Square again then this message was repeated (ad infinitum), otherwise the program accepted their new selection and the test ended. The dependent variable was scored in three steps: correct at first attempt, correct at a subsequent attempt, and not correct at first or following attempts (which were given the scores 1, 2, and 3, respectively). For each correctly identified pair, the cards were removed and two blank spaces were left in the position where they had previously been placed. The dependent variable is thus the number of errors made before all the pairs had been matched. We considered the three-pairs round a warm-up trial for the six pairs round, which constituted the dependent variable.
