New technology to help combat one of the first signs of hearing loss
The new technology helps to tackle one of the first signs of hearing loss making it easier for the user to focus
Nuance Hearing launches state-of-the-art directional microphone to help address the ‘cocktail party problem’ which can lead to further hearing loss
The Voice Selector Converse created by Nuance Hearing helps overcome hearing situations such as the cocktail party problem. It offers a tech solution to understanding conversations in a crowded room eliminating the need for hearing aids. Research shows that 41 per cent of UK adults admit to having a problem understanding speech in a noisy environment. Over one third said that noisy environments caused them stress and anxiety with a further 60 per cent saying they would be open to trying tech to help them hear.
The Voice Selector Converse uses built-in microphones and an advanced algorithm to track the source of sounds allowing the user to focus on a conversation while tuning out background noise. The cocktail party problem is an inability to understand speech when a person is in a noisy environment. It is estimated to affect up to 41 per cent of adults.
Nuance hearing testing
In audiology testing, users were able to understand speech three times better with the product rather than without. The cutting edge beamforming technology features eight built-in microphones that track the source of sounds while reducing the background noise level. The result is a world-leading directivity index, the relative reduction of overall noise in relation to the target sound, of 115dB in real-time performance. This is in relation to an industry standard of 4-5dB.
The improvements help the listener to focus and effortlessly tune out the sounds that do not matter rather than those that do.
The Voice selector Converse has unique auto-steering technology that picks up the dominant speaker even when they are moving about. Alternatively, the user can manually switch between speakers when in a group of multiple speakers. It can capture, process and play audio at a record speed of six milliseconds while being used as a table or remote microphone.
Ori Goren, CEO of Nuance Hearing, said: “Since 2015, we have been delivering powerful and advanced hearing solutions that deliver optimum performance. We know that many people in the UK are suffering in silence, unable to feel comfortable or enjoy conversing in busy environments, and are proud to have launched an innovative tech solution to help combat this.
Through innovative technological solutions, we are passionate about improving the quality of life for a diverse group of people, making every environment more accessible and helping ensure personal success and empowerment.”
Hearing loss is estimated to affect 12 million people in the UK. The World Health Organisation (WHO) estimates that one in every five people worldwide live with hearing loss which is expected to rise to one in four by 2050. On average, people wait for ten years before getting help with hearing loss.
Hearing loss can have a devasting impact on people’s ability to communicate, study or earn a living. It also has an impact on people’s mental health and ability to sustain relationships. It has been linked to faster cognitive decline.
Hearing loss problems
Franki Oliver, audiology specialist, RNID, said: “While it might not seem obvious at first, having difficulty understanding speech in background noise is usually one of the early signs of hearing loss. The ‘cocktail party problem’ is the name used to describe the brain’s inability to filter out background noise and tune into what someone is saying in a busy environment. Most people with hearing loss experience difficulty in these situations.
He added: “It’s important to check your hearing if you start to notice difficulty in background noise, feel that people mumble, or you ask people to repeat themselves. It’s second nature for people to have their eyes checked regularly but we don’t have the same attitude towards getting our hearing checked yet.
The sooner hearing loss is identified, the earlier someone can start benefiting from life-changing hearing devices. Hearing loss can also be linked to conditions such as dementia so early intervention is vital.”
Gut-friendly foods such as kimchi and kombucha may carry hidden risks for heart health when eaten in excess, the British Heart Foundation (BHF) has warned.
The charity said foods marketed as prebiotic, probiotic or otherwise good for the gut can support the microbiome, but some may also be high in salt or sugar, which can raise the risk of cardiovascular disease.
Products highlighted by the British Heart Foundation included kimchi, kombucha, fruit yoghurts, smoothies and sauerkraut. It said there is no harm in including them as part of a healthy diet, but advised people to check labels for added salt and sugar and eat them in moderation.
Tracy Parker, the charity’s nutrition lead, said: “We encourage everyone to choose foods that can keep their gut microbiome healthy. The benefits are clear, and we are continuing to improve our understanding of how a gut-friendly diet may help our hearts.
“A lot of these products can contain high levels of salt or sugar though, so it is important to be aware of the potential drawbacks.
“By ensuring you check package labels for added salt and sugars, and eat each in moderation, you can make sure the risks do not outweigh the benefits for your heart health.”
Fermented foods such as kimchi and sauerkraut are rich in probiotics, the healthy bacteria produced during fermentation that can help support a diverse and healthy gut microbiome.
However, both are traditionally made using a lot of salt, which can raise blood pressure if eaten frequently or in large quantities. High blood pressure is known to increase the risk of heart attack and stroke.
Kombucha, a fermented tea, also contains probiotics and can be a healthier alternative to fizzy drinks, but many commercial and shop-bought versions contain added sugar.
Eating too much sugar can lead to weight gain, which can increase the risk of heart attack, stroke and other cardiovascular disease.
Fruit yoghurts can contain probiotic live bacteria cultures, but may also be high in sugar and have fewer live cultures than plain versions.
The charity said plain yoghurt with live and active cultures on the label can be a lower-sugar option, with whole fruit added at home for sweetness.
Smoothies made with whole fruits provide prebiotic fibre, which feeds beneficial gut bacteria and supports digestive health.
They can also provide vitamins and antioxidants, especially when made with a variety of plant-based ingredients.
But blending breaks down the structure of fruit, releasing free sugars that behave like added sugars in the body and can cause faster rises in blood sugar levels.
Regularly consuming too much sugar can lead to weight gain, which can increase the risk of developing type 2 diabetes, heart disease and kidney disease.
The charity said only one 150ml serving of any smoothie counts towards five-a-day, and suggested adding nuts or seeds for extra protein and fibre to help keep blood sugar levels more stable.
The BHF also noted that some shop-bought sauerkraut is pasteurised, which removes most of the live bacteria.
It advised checking the label, eating small portions and choosing unpasteurised products for those seeking the probiotic benefits.
The charity said beneficial gut bacteria produce short-chain fatty acids during digestion, which are linked to reduced inflammation, better metabolism and better heart and circulatory health.
These good bacteria also help digest polyphenols, natural plant chemicals thought to have antioxidant properties and which may help lower blood pressure.
By contrast, harmful gut bacteria, which thrive on diets high in fat and red meat, produce chemicals that can cause problems in the heart and blood vessels by increasing inflammation and altering how cholesterol is processed in the body.
Beneficial bacteria thrive on varied diets high in prebiotics, non-digestible fibres found in foods such as wholegrains, oats, beans, lentils, bananas and onions.
People with diabetes may have undiagnosed heart failure that could be detected by a simple screening blood test, research suggests.
The TARTAN-HF trial found that one in four patients with diabetes who had at least one other risk factor for heart failure had undiagnosed heart failure detected through screening with a blood test and ultrasound scanning of the heart.
Experts said the findings show the extent of unrecognised heart failure in people with diabetes, and how the condition can be detected using a widely available blood test called NT-proBNP, which measures how much strain the heart is under.
They suggest a heart failure screening programme for diabetics could improve diagnosis rates, lead to earlier treatment and potentially reduce the risk of hospitalisation and death.
The study, involving 700 patients, was led by the University of Glasgow in collaboration with AstraZeneca, Roche Diagnostics, Us2.ai, NHS Greater Glasgow and Clyde and NHS Lanarkshire.
Dr Kieran Docherty, clinical senior lecturer at the University of Glasgow’s School of Cardiovascular and Metabolic Health, said: “Our results from the landmark TARTAN-HF trial identified heart failure in a large proportion of people living with diabetes, emphasising the need for a heart failure screening strategy in this group of patients.
“We know that many of the symptoms and signs of heart failure are non-specific, and may go unrecognised as potentially being due to heart failure for a long time.
“The strategy used in our trial is simple and easy to implement in clinical practice, and will aid in the early identification of heart failure in people with diabetes, and facilitate the initiation of medications that we know improve outcomes in patients with heart failure.”
The study, which began more than three years ago, involved more than 700 people with diabetes from the two health board areas who had at least one other risk factor for heart failure.
They were randomly assigned either to receive heart failure screening or to continue with their usual care.
Researchers found screening uncovered a large number of previously unrecognised cases of heart failure. Around one in four, or 24.9 per cent, of those screened were found to have the condition within six months, compared with 1 per cent in the group continuing their usual care.
The study, involving patients with type 1 and type 2 diabetes, found almost all of the participants found to have heart failure had preserved ejection fraction, which can be difficult to detect without dedicated testing.
The findings of the TARTAN-HF trial were presented at the American College of Cardiology conference taking place from 28 to 30 March in New Orleans in the US.
Dr Edward Piper, medical director at AstraZeneca UK, said: “Delayed diagnosis and treatment of heart failure in people with type 2 diabetes contributes to poor long-term outcomes. TARTAN-HF demonstrates that targeted, risk-based screening can identify previously undiagnosed heart failure in approximately one in four high-risk patients with diabetes, enabling earlier intervention with guideline-directed therapy.”
Dr Christian Simon, head of global medical affairs at Roche Diagnostics, said: “We are proud to have supported the landmark TARTAN-HF trial. These findings demonstrate the transformative power of early, accessible diagnostics like the NT-proBNP blood test.
“By identifying unrecognised heart failure in people with diabetes, we enable clinicians to initiate appropriate treatments sooner, ultimately improving patient outcomes and lives.”
The UK has launched a £6.3m men’s health fund to back local projects aimed at helping men and boys live longer, healthier lives.
The Men’s Health Community Fund is a partnership between the Department of Health and Social Care, Movember and People’s Health Trust.
The government is contributing £3m, while the two charities are more than doubling that to take the total to £6.3m.
Grants will support community projects reaching underserved men and boys aged 16 and over, particularly in the most disadvantaged areas and at key points in their lives such as becoming a father, losing a job or retiring.
Projects could include support for new fathers, activities for men facing loneliness and social isolation, services to help young men engage with the health system, and support for men in work, out of work and moving into retirement.
The programme will bring together voluntary, community and social enterprise organisations to test new ways of reaching men who are least likely to use traditional health services.
An evaluation funded through the National Institute for Health and Care Research will assess what works and help inform future policy and delivery.
Health and social care secretary Wes Streeting said: “Too many men across the country are living shorter, less healthy lives, particularly those in our most disadvantaged communities.
“This new partnership will help men get the support they need in the places they feel most comfortable, their communities, among people they trust.
“By working with expert charities and local organisations, we can reach the men who are too often missed by traditional services and help them take better care of their mental and physical health.”
“It is a key step in delivering our first ever Men’s Health Strategy and driving forward our ambition to halve the gap in healthy life expectancy between the richest and poorest areas.”
The Men’s Health Strategy sets out plans to tackle the physical and mental health challenges men and boys face.
Men can be less likely to seek help and more likely to suffer in silence, while higher rates of smoking, drinking, gambling and drug use are damaging men’s health and affecting families, workplaces and communities.
The government is also investing £3.6m over the next three years in suicide prevention projects for middle-aged men in local communities across areas of England where men are most at risk, many of which are also among the most deprived. Suicide is one of the biggest killers of men under 50, and three-quarters of all suicides are men.
The projects will aim to break down barriers middle-aged men face in seeking support, including stigma around asking for help and a lack of awareness of what is available and how to access it.
They will be co-designed with experts and men with lived experience of mental health crises and suicidal thoughts.
