SNR Hearing Loss? Hearing Loops Help

What is SNR Hearing Loss?

SNR stands for Signal to Noise Ratio. In the case of hearing loss, the “signal” that is all important is the speech signal. And so, SNR Hearing Loss refers to a most frustrating issue, namely “ the inability to understand speech in background noise.” Speech signals are drowned out by competing sounds and the more hearing loss a person has the more garbled speech becomes.

“SNR Hearing Loss,” is an expression that is used more commonly nowadays and therefore it must be introduced into the vocabulary of those with hearing loss. In a way, an old familiar problem gets a name.

SNR Hearing Tests

SNR losses tell by how much the speech signal must be raised over background din for speech to be understood. Audiologists can actually measure SNR losses with tests that go beyond the standard tests that are usually performed in a quiet or even soundproof place. Such a scenario obviously does not reflect the realities of everyday life.

During these tests, the patient repeats short sentences against increasing levels of competing background sound. The resulting scores tell the hearing specialist how much loss there is and what type of help the patient needs. The aim is to bring the SNR into a range that makes it easier to understand speech in noise.

Often, the frustration for patients is that even perfectly tuned hearing aid features are not powerful enough to boost the SNR in noisy places. In those cases, other hearing strategies and/or assistive technology are needed, such as the use of an auxiliary microphone.

Certainly, the background noise can be lowered or even turned off but in most cases that is not possible. One can get close enough to face a conversation partner in order to lip-or speechread, which is not very practical in large venues. And now, COVID safety practices do not allow for that approach.

Hearing loops help

The nature of hearing loops is that they greatly reduce background sound and even eliminate it. Only what goes into a speaker’s microphone goes into the telecoils in hearing aids or implanted devices.

The sound signal of a correctly installed hearing loop is even and a lot clearer and stronger than what hearing aids might deliver. With a loop it does not matter how far away the telecoil user is from the speaker. In a looped area anybody with telecoils – in hearing instruments or in portable devices – can listen without strain or struggle. Even people with severe hearing losses report greatly improved listening experiences in looped venues.

Time to learn and to be included in conversations

As COVID-19 winds down ever so slowly and society opens up, people with hearing loss do not want to be left out and isolated again. This is a good time to learn about Loop technology and to advocate for the installation of hearing loops in places where we need to hear and understand better: Library lecture rooms; places of worship; event halls; courts of law etc.

And so, there is no time like the present to work on getting into the loop and to create our communication future.

COVID Homebound? Learn About Neckloops

Loop Minnesota Posted on by

Learn About Neckloops

Got telecoils in the hearing aids but no loop at home with which to use them? Learn about the induction neckloop, which could be a very helpful tool for those who do not have Bluetooth hearing aid connectivity for streaming over short distances.

What is a neckloop?

A basic, non-amplified neckloop is a miniature version of a large loop, such as a room loop. It is an electrical wire that is worn unobtrusively around the neck, under a shirt maybe. It has a plug that connects to different sound sources, such as personal FM amplifiers, phones, MP3 players, laptops, TV etc.

The sound source energizes the loop wire. Users activate the telecoils by switching the hearing aids or cochlear implants into T-mode or T/M mode. The telecoils tap into the magnetic field generated around the wire and pick up the refined audio signal for much clearer listening.

Of course, there are all sorts of assistive devices on the market. However, at a cost of less than $50, I find that my neckloop (pictured above) was a good investment. When I do Zoom presentations, the loop is plugged into the laptop headphone jack. It is invisible to the audience and so is the wireless communication between the neckloop and the hearing aid Telecoil. Discussions that all too often take place in low-quality sound environments become a lot easier to follow.

Complexity and compatibility

More advanced neckloop versions incorporate a microphone and amplifier button or wheel. These are often referred to amplified or powered neckloops. They cost more than the basic version and the larger mic/amplifier portion is visible. But they do have their advantages.

People who use such loops regularly for easier communication, especially at work, share that they are great for one-on-one communication, while being socially distanced. An amplified/powered neckloop could be quite helpful at the doctor’s or lawyer’s office or when visiting with a friend. They also facilitate hands-free telephone conversations that will be heard in both ears if the user has two hearing aids with telecoils.

Amplified/power neckloops must be matched to the devices and phones to which they will connect. Compatibility is key and so it is important that the correct connector cables are provided or purchased. Read the fine print!

Making the most of the devices that we have

People with hearing loss know that change is constant, especially when it comes to changes in hearing technology. Yet, it does not always have to terribly expensive and over-the-top complicated. For the price, neckloops can help us make the best of all sorts of hearing gadgets that we have already stashed around the house.

Do some research. Look at the websites of the many companies that deal with this technology, such as these local providers:

harriscomm.com

williamsav.com

Also, talk to the audiologist about neckloop options and assistive listening devices (ALDs).

However, for any loops to work, we must remind audiologists that we need telecoils in our hearing aids and cochlear implants – tuned to our hearing loss and activated.

And so, spend a few moments googling the topic because in the World of Hearing Loss learning never stops. Contact us at loopminnesota.org to learn more.

Hearing Loops for Businesses

Hearing Loops for Businesses

Shortcomings in equitable access

Although totally necessary, COVID-19 safety precautions have led to serious communication issues for those with hearing challenges ─ over 20 percent of the population.

While all customers and clients need equitable access to communication at any time, the Coronavirus has uncovered the fact that many businesses have few if any ways of accommodating hearing loss for everyday business transactions.

No more lipreading

Speechreading (lipreading), an important communication method for those with hearing loss has become pretty much impossible these days. Keeping at a distance weakens sound signals, which are further muffled by facemasks and plastic or glass barriers. Facial expressions are no longer visible. And then, there is no other accommodation!

Even as the COVID pandemic rages on and safety precautions are all important, tending to daily business should not be a dreaded chore because of lack of access. And that access should be discreet, wireless and touchless while providing sound clarity.

Counter Hearing Loops can help.

These have been around for some time and are very common overseas. They are simpler, faster and less expensive to install than whole area loops. There are even portable versions.

Clients can tune into the loop sound signal by activating the telecoils in their hearing aids, cochlear implants or portable T-coil devices. No yelling. No overly amplified, embarrassing cacophony. No need for unhygienic access devices.

Get information

When it comes to sound access, every situation is different. Therefore, it is important to do some research and to get information from knowledgeable sources. Get started by Contacting Us.

Advertise!

Once counters or kiosks have been made accessible, include this information in your advertising material. Let people with hearing loss know that you are inclusive and that equitable access is an important business concern.

The blue-and-white hearing loss symbol marked with a prominent “T” (for telecoil or T-coil), tells customers that they have loop access and which waiting line or service desk to choose.

COVID-19? Need for Hearing Loops & T-coils

COVID-19? Need for Hearing Loops & T-coils

Growing communications challenges

As the COVID-19 pandemic rages on, communication challenges of all kinds have turned into an acute issue for those with hearing loss. Speechreading (lipreading) has become impossible during these times of social distancing, masked outings and muffled conversations. Being talked to through plastic or glass partitions contributes to the further dulling of sounds.

As society gradually reopens ever so hesitantly, continued distancing and mask requirements will remain in effect and so will the communication hurdles. Sitting up front, close to the speaker is a thing of the past. “Up close” is a lot further back these days.

Now is the time to advocate for communication access

Wouldn’t it be nice to connect via telecoil or T-coil to hearing loops installed at bank and pharmacy windows, at information desks, in class rooms, libraries, places of worship and in health facilities? Gone would be the background noise and speech would be so much easier to understand – without the struggle, the fatigue and the embarrassment. Hearing loops are especially helpful in large, noisy venues such as convention and meeting rooms.

It is often said that anybody who has ever listened to speech through a correctly installed hearing loop does not want to turn back. As we go forward into a shaky communication future, it is more important than ever for people with hearing loss to get involved and to stand up for communication access. Let’s not be left out – again!

Visit this website and learn about it

The problem is that many people do not know much – or anything at all -about this technology. Non-proprietary hearing loops are different from proprietary, short-distance Bluetooth. A hearing loop is a special electrical wire that is installed throughout or around the area that is to be made accessible.

Telecoils or T-coils are tiny wireless antennas that can be found in cochlear implants, hearing aids and hearing devices large enough to accommodate them. They allow the user to tap into the sound energy carried by the magnetic field that surrounds a hearing loop that is in active service. Together, loops and telecoils act as assistive listening “systems.”

Do your hearing aids have telecoils?

Find out! Now is also the time to ask hearing specialists if the hearing aids that you plan to buy – or have already bought -have telecoils. Most people do not know because they have never told about them. Yet, in order for them to work, the hearing specialist must “activate” the telecoils and tune them to the hearing needs of the client. He/she must also instruct the client on how and where to use them.

The future of access is up to the people

In the end, do people with hearing loss want to be connected and included as communication snags pile up? If yes, it is time to act. Hearing loops do not magically appear. The technology needs advocates and believers who make the case for much-needed accessibility.

And so, what will our communication future look like? As President Abraham Lincoln told us “The best way to predict the future is to create it.” And the time to become “creative” and motivated is now.
