Can COVID-19 Worsen Tinnitus?

Roughly one in five Americans experience tinnitus, the perception of noise in the ears frequently compared to a ringing or similar sound. Many factors contribute to tinnitus; now, we can add COVID-19, thanks to a recent study from Angela Ruskin University in Cambridge, England.^[1]

The study, which looked at 3,103 people with tinnitus from 48 countries, was conducted in cooperation with both the British Tinnitus Association and the American Tinnitus Association. The results, published in the medical journal Frontiers in Public Health, found that 40% of COVID-19 patients experienced an increase in tinnitus symptoms.

While the majority studied in Cambridge had already been diagnosed with tinnitus, a small number appeared to have developed symptoms due to the coronavirus, leading researchers to speculate that tinnitus may be an additional, though somewhat rare, symptom of COVID-19.

Social distancing was another contributing factor to increased symptoms, according to a significant number of tinnitus sufferers whose work and lifestyle routines were disrupted (46% of UK patients and 29% from North America). Stress, loneliness and difficulty sleeping made tinnitus more bothersome for 32% of respondents.

Other factors mentioned by participants that exacerbated tinnitus symptoms include increased video calls, noisier home environments, homeschooling, and increased coffee and alcohol consumption. Along with the challenges in accessing health care due to COVID-19 restrictions, it’s clear the pandemic impacts those with tinnitus across the globe.

“Some of the changes brought about by COVID-19 appear to have had a negative impact on the lives of people with tinnitus, and participants in this study reported that COVID-19 symptoms are worsening or, in some cases, even initiating tinnitus and hearing loss,” explained Dr. Eldre Beukes, a research fellow at ARU and Lamar University in Texas and lead author of the study.

With a long list of possible causes, it’s best to schedule an appointment with Center for Hearing to get to the root cause of your tinnitus.

The Future of Hearing Devices: Deep Neural Networks & Artificial Intelligence

February 14, 2025

Hearing technology has come a long way over the years; however, one aspect of hearing loss that many hearing aids have difficulty addressing is trouble understanding speech in noise. Fortunately, some of today’s state-of-the-art devices can solve this problem utilizing deep neural networks (DNN) and artificial intelligence (AI). Sensorineural hearing loss causes difficulty understanding speech in background noise. This type of hearing loss is caused by damage to the hair cells of the inner ear that convert soundwaves into electrical energy, which are then interpreted by the brain. This causes the quality and quantity of the signal sent from the ears to the brain to diminish over time, resulting in the brain expending more energy and effort to make sense of it. DNNs may help improve the transmission of the neural code, making hearing easier on the brain. [1] It’s important to know what DNNs are to understand how they can help. DNNs are a subset of AI. They rapidly analyze large data sets so that they can teach hearing aids and other technological devices how to respond to data like a human would, all while verifying accuracy and making corrections. DNNs are beneficial in hearing technology because they can help with speech enhancement. DNNs can be applied as “time-frequency masks,” meaning select sounds—like speech—are allowed while other sounds are suppressed. DNNs can also identify and separate multiple voices, selecting a primary voice to emphasize and secondary voices to suppress. This feature can help hearing device wearers in a variety of settings. For example, at a restaurant or party, the hearing device can emphasize a conversation partner, allow other nearby voices at a reduced volume and suppress background noises such as dishes clinking.

Startup Aims to Develop the First Gene Therapy for Hearing Loss

February 14, 2025

A Boston biotech startup is attempting to develop the first gene therapy treatment for hearing loss. If successful, it promises to offer new hope to the estimated 300,000 Americans who suffer from gene-based hearing loss—a number that includes more than 4,000 newborns. The timing may not be ideal, but biotech companies have been largely immune from the effects of the COVID-19 pandemic and ensuing recession. Developing new drugs takes years, so these companies are better able to weather storms. And the efforts of biotechnology companies that are focusing on tools to prevent and treat potentially fatal health threats has resulted in soaring stock values for many of these companies, even in the face of the current crisis. Akouos, the Boston startup, was founded in 2016. Its goal is to develop the first gene therapy to treat hearing loss and is targeting a specific form of deafness that results from mutations in a single gene. They are experimenting with adeno-associated viruses, using them as vectors to deliver DNA that encodes a functioning gene in certain target cells. Around 7,000 people are afflicted with this type of genetic hearing loss. Adeno-associated viruses are considered viable candidates because they don’t usually cause disease and can be customized to treat a variety of genetic conditions. The company has partnered with two influential organizations: Massachusetts Eye and Ear and Lonza, a Swiss manufacturing company that holds contracts with various pharmaceutical makers. Manny Simons, Akouos’ co-founder and chief executive, holds a degree in neuroscience from Harvard College, a Ph.D. in biomedical engineering from the Massachusetts Institute of Technology, and an MBA from Harvard Business School. His desire to help those with hearing loss stems from his passion for playing the piano. “It’s easy to take hearing for granted,” said in a Boston Globe interview. “Maybe because music has been important to me, it’s something that I take a little less for granted.” [1] [1] Saltzman, J.
