Bluetooth is a wireless technology that allows electronic devices such as mobile phones, computers, satellite navigators and digital cameras to connect to one another.
A bluetooth connection works within a set distance and has a number of features which can simplify our daily lives.
It is often necessary for hearing aid wearers to take off their hearing aid, or hold their mobile phone in an awkward position, because cell phones tend to create so much feedback in the hearing aids that listening to conversations can be difficult. With bluetooth wireless connectivity and a high quality microphone built into the bluetooth remote, a pair of hearing aids can instantly transform into a small wireless hands-free for mobile phones, with clean and clear sound - in both ears - making it easy to use for people with hearing aids. Leading mobile handset producers expect that more than 50% of more than a one billion global sale of mobile phones will be BluetoothTM enabled.

Finally, hearing aids for people with sensitive ears and those who "cannot stand anything in their ears".
DiMarco uses the universal language of dance to change the hearing world’s perception of what it means to be Deaf – and he just might win the Mirrorball trophy in the process. Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too.
Hearing aids are available along a continuum of technologies, from basic features like noise reduction to advanced features like Bluetooth compatibility. Hearing aid technology has changed a lot over the past few decades, but at their core, hearing aids have always been made of four basic parts: a microphone, a processor, a receiver and a power source. The bulk of the technology that is packaged into a hearing aid resides in the part that is called the processor. Hearing aid technology can be broadly divided into basic and advanced groups, based on the sophistication of features available in the processor.
Basic digital hearing aids generally require the wearer to make some manual adjustments in certain listening situations—such as turning a volume control up or down, or pushing a button on the aids in order to reduce noise coming from behind the wearer. The following are examples of features that are usually included in basic hearing aid technology. The number of channels represents the number of discrete sections that can be used for processing different parts of the incoming sound signal.
Directional microphone systems are designed to give a boost to sounds coming from the front of the wearer and reduce sounds coming from other directions. Digital noise reduction systems analyze the signal to determine if it contains unwanted noise. Similar in purpose to the digital noise reduction, impulse noise reduction seeks to improve listening comfort.
Feedback management systems are used to combat the inevitable feedback loops that occur when a microphone and speaker are placed in close proximity, as they are in a hearing aid.
Telecoil is a wireless feature that picks up electromagnetic signals from compatible telephones or looped rooms. Frequency modulation (FM) compatibility is a wireless feature that enables hearing aids to connect with FM systems, sometimes via a special attachment to the hearing aids called a boot.
As mentioned above, several of the basic hearing aid technologies can be implemented in very sophisticated ways.
In addition to the basic hearing aid technology, each major hearing aid manufacturer offers several levels of advanced digital technology. Bluetooth compatibility is a wireless feature that enables hearing aids to connect to mobile phones and other devices that use Bluetooth, often through an intermediary device. Although fairly specific in its application, wind noise reduction can make a world of difference for those who spend time enjoying outdoor hobbies, like golfers and boaters. Data logging is a feature that stores data about the listening environments in which you wear your hearing aids and your preferences for programs, volume levels and other features. Binaural processing is generally used to describe any situation in which a pair of hearing aids communicates wirelessly with each other. Each design application has its own particular demands and requires a special combination of tools to achieve excellence.
Constant review and evaluation of designs and approaches requires simplifying CAD designs, analyzing acoustics and vibration, and using a specialized algorithm-development and simulation environment. Finding the Right Tools for the Job Hearing aid developer Widex infuses expertise and creativity in the advancement of these electroacoustic devices and ensures high performance through rigorous analysis, enabled by 3D direct modeling. The American Academy of Audiology estimates that 36 million Americans require hearing aids, and as the Baby Boomer generation grows older, the number of people with hearing impairment and loss increases rapidly. The 3D Design Challenge Mads Jakob Jensen is a development engineer who has been working with Widex for more than three years.
Jensen uses COMSOL primarily to analyze acoustics and vibrations to optimize hearing aid performance. Model Preparation Jensen chose SpaceClaim 3D Direct Modeling software to reduce the time required to analyze single geometries.
Jensen now spends more time analyzing and improving hearing aid designs and less time preparing and transitioning, enabling him to focus his skills and creativity on the task at hand. COMSOL and SpaceClaim Once the model is prepared in SpaceClaim and ready for analysis, Jensen uses COMSOL Multiphysics’ PDE mode and transfers the results to a specialized simulation and algorithm-development environment that Widex assembled and built on MATLAB. Prior to using COMSOL, the algorithms used for these procedures were based on experimental measurements gathered from lab tests that didn’t capture all the complexities required to adequately analyze the hearing aids.


All this development leads to the ultimate goal of creating the most efficient device to help people enjoy and fully use their sense of hearing. Records Hearing Aid usage information like duration of use per day, duration of usage of specific programs, volume changes and how long you spend in specific environments. Makes automatic adjustments to your Hearing Aids program based on your corrections over time. Lets you fine-tune yourself all Hearing Aid parameters via an intuitive interface on an iPad or PC. Allows you, with the press of a button, to verify if all the components of your Hearing Aids are working to specification.
Based on your actual hearing loss, the fitting software is able to simulate to your family and loved ones how you actually hear and which sounds are inaudible or distorted to you. Instead of indicating program or battery status via a sequence of sounds the Hearing Aid uses speech to convey the message clearly to you. 91% of all subjects reported a reduction in Tinnitusthis will be written under clinical evidence.. Download a copy of the Tinnitus Reaction Questionnaire (TRQ) and see what your score is now. More and more devices are being fitted with bluetooth technology to make our lives that little bit easier. The microphone picks up the sounds in the wearer’s environment and passes it to the processor. The processors today are more programmable than ever before, allowing the hearing care professional to precisely fine-tune the amplification characteristics and customize other special features based on the individual needs of the wearer.
Even today’s basic digital hearing aids offer way more benefit to individuals with hearing loss than the best hearing aids of previous generations. The processor may separate incoming signals into two or more channels and process each channel separately. The more channels in a hearing aid, the greater the flexibility in programming, as the hearing aid prescription can be customized across the different frequencies, or pitches. Different system designs block out more or less of the sounds coming from behind the wearer.
This system detects any transient loud noises, such as car keys rattling, typing on a keyboard or dishes rattling, and soothes them out so they don’t startle or annoy the hearing aid wearer. These feedback loops create an annoying whistling sound that can get in the way of listener comfort. This technology has been available in hearing aids for a very long time and can often be included in very basic models. As the level of technology increases, hearing aids become more automatic and are equipped with more features to help individuals better communicate in difficult listening situations. More advanced technologies translate to higher price points for hearing aids as well as greater benefits.
Like telecoil and FM compatibility, Bluetooth technology has the ability to improve the signal to noise ratio and eliminate feedback from the microphone because the signal bypasses the microphone and directly enters the hearing aid’s processor.
Wind noise reduction is an advanced hearing aid technology that detects the impact of the wind blowing across the hearing aid microphones and avoids or reduces the amplification of it. The information can be accessed by the hearing healthcare professional when you return for a follow-up appointment. By logging volume control settings and program preferences for certain sound environments, the hearing aids can begin to make these changes automatically when the environment is detected. This relatively new technology has a lot of potential for improving the wearer’s experience because the hearing aids can access information from both sides of the head. Sounds are coming from all directions, such as dishes clanking, people talking and laughing at other tables and waiters rushing about.

Download our free guide, which will give you the information you need to help your family member or friend with hearing loss. The optimization of hearing aid designs calls for a unique skill set—the ability to perform basic functions in one area but extensive expertise and creativity in others.
To meet these needs, the hearing aid technology developer assembled a collection of tools that provided flexible and easy-to-use interfaces, interoperability, and specific technical functionality. As a result, the need for quality products that help individuals overcome these physical problems has never been higher, and companies such as Widex are investing the time and effort required to perfect the technology. As part of the process of preparing the model for analysis, he must simplify the existing design, which is sent to him in one of the many CAD formats. More time is spent evaluating the advantages and opportunities to improve each hearing aid model and less time waiting for the models to go through CAD systems to be prepared for analysis.
The equations used in these studies are not standard in most commercial simulation software, but they integrate with COMSOL Multiphysics to enable Jensen to study the acoustic model of the ear and optimize the design of the hearing aid. Because COMSOL Multiphysics enables us to input our own equations, it has been essential to our studies,” says Jensen. COMSOL enables Jensen to study more details that are difficult to acquire experimentally, including radiation from the ear mold and internal structural vibrations. SpaceClaim perfectly complements COMSOL to prepare models for performance-intensive analyses.


This data can be read out by the fitter and used to make automatic or manual changes to the program to improve your hearing and convenience.
Transient Noise Reduction can effectively reduce such transient noise, giving the hearing aids wearer more listening comfort. The device comes with 4 different musical tracks fully personalized depending on individual’s hearing level and tinnitus.
The processor enhances the signal and delivers it to the receiver which delivers the amplified signal to the ear canal.
The practitioner programs the hearing aids by connecting them to a computer and detecting them with special software provided by the hearing aid manufacturer. For example, a basic two-channel instrument may be programmed to give more amplification for high-frequency sounds than it gives for low-frequency sounds, in order to accommodate an individual’s hearing loss. Feedback management algorithms can be implemented differently for basic hearing aids or advanced hearing aids.
Because the signal of interest is directed to the hearing aid’s processor without using the microphone, telecoil can improve the signal to noise ratio while eliminating the potential for feedback.
Like telecoil, FM systems improve the signal to noise ratio without causing a feedback loop in the hearing aids. For example, instead of utilizing two channels to separate sound for processing, a hearing aid with advanced technology may have eight or more channels. The following are examples of features that are more likely to be offered in advanced hearing aids.
A Bluetooth connection is also less likely to experience interference, which can occur with an FM system. Your practitioner will use this valuable information to further customize your hearing aid fitting.
The goal is to reduce the amount of manual adjustments the wearer is required to make over time. It is most commonly used to keep the hearing aids operating synchronously (such as switching from program 1 to 2 at the same time) or to stream auditory signals from one hearing aid to the other.
You’re wearing your new hearing aids and listening to a friend who is sitting across from you at the table. This software mix streamlined development processes, reduced cycle time, and optimized the use of resources. With most behind the ear (BTE) models, the electronics on the outside of the ear connect to a mold on the inside via a tube. Jensen is not a CAD expert, and when he received the existing designs, he had to send them to the design department to be de-featured and simplified so that he could perform what-if analyses. The algorithms permit optimization of everything from the location of the microphones on each hearing aid to the location of miniature vents that reduce low-frequency sound at the eardrum. Jensen is able to ready models quickly without getting bogged down in the complexity and compatibility issues inherent with traditional CAD systems.
Hearing aids are nano-coated inside out to protect them against moisture, dust and sweat, which reduce the risk of failure due to moisture and resulting in corrosion.
You can get almost any hearing aid processor tucked into whatever hearing aid style you prefer.
Although programmable by computer, basic hearing aids generally have limited adjustments available for fine-tuning to fit unusual patterns of hearing loss. Basic feedback management systems may reduce the overall amplification in order to remove the whistling.
Public performances, tours, exhibits and worship services are commonly made accessible to individuals with hearing loss via telecoil. FM compatibility is especially important when selecting hearing aids for children because these systems are commonly used in educational settings to ensure that the teacher’s voice is heard above the clamor of the classroom.
This splits the signal into even smaller frequency bands and therefore offers a higher resolution of signal processing. Inevitably, a small amount of sound leaks out around the mold, reducing the sound transmitted to the eardrum and potentially interfering with the exterior microphone, causing grating sounds for the user. This process was time consuming and resulted in lengthy and frustrating delays before he could proceed. After performing analysis and design edits, he is able to provide a final model that specifies the detailed design in CAD, eliminating the time-consuming back-and-forth processes and expediting time to market. The digital age has transformed these four basic parts into four very sophisticated components. Advanced feedback management systems reduce or eliminate whistling without affecting overall amplification of the hearing aid.
Your hearing aids are simultaneously reducing impulse noises like silverware clanking onto a plate (impulse noise reduction), reducing the whir of the ventilation system above (digital noise reduction), suppressing the voices of the people at the tables behind you (directional microphone system) and storing information about the listening environment to be saved for later fine-tuning (data logging). For example, virtually all hearing aids on the market today are digital, meaning the signal picked up by the microphone is converted from analog to digital before being processed, then converted back from digital to analog before the receiver delivers the enhanced signal into the ear canal.
They’re doing all of this automatically while amplifying and shaping the speech signal from your friend.
