“Binaural beats did seem to change the way participants’ brains processed information during the study, but it didn’t necessarily make it better,” Smith says. Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments.
Hearing aids are technologically advanced assistive devices that are on the same level as modern computers. Those old-looking devices with outdated technology have come and gone. Today’s hearing aids are far more than simple audio amplifiers; they now come loaded with a number of special features that enhance performance and usability.
Below, you can read about what binaural hearing aids offer and how they can make your listening experience much more pleasant. Of course, our hearing aid experts are available to help you with any questions related to hearing loss – free of charge and without obligation.
Outdated hearing aid models – individually and independent of each other – amplify sounds. However, modern binaural hearing systems, similar to natural hearing, couple the left and right hearing aids together via a radio signal. The devices are able to intelligently communicate and coordinate with each other. The important thing to remember is that hearing aids are medical devices and most people suffer from bilateral hearing loss so they should get a hearing device for each ear rather just one device. Just like if you had blurry vision, you wouldn’t wear one eye glass, similarly hearing loss should be treated binaurally.
Hearing aids have been around for a long time but with so many advances in technology, there are so many options available for hearing systems. When the devices were first manufactured, they were monaural devices. That means that the devices worked individually and if a person was wearing two devices they wouldn’t connect to give an overall, surrounding sound. This meant the wearer could feel quite overwhelmed with all the different information being passed to the ear. However, the latest technology of binaural aids mean that the devices in the two ears are connected to give an overall sound. This ensures that the wearer is able to understand the surroundings without being overloaded with too many different sounds.
Due to the signals from both ears, the auditory center in the brain manages to adequately filter speech from sound and suppress background noises. In this way, speech intelligibility is also significantly improved, even in acoustically demanding situations. Do you feel uncomfortable when you are at a restaurant, in a full train, or in crowded and noisy public places, because you feel you are unable to understand the people with whom you are speaking? We can change that with the help of a binaural hearing system.
The direction of the microphone normally corresponds with the hearing aid wearer’s line of sight. But if you are sitting at your personal computer and concentrating on the screen, and still want to converse with a person behind you, the older hearing systems will not be of much use. Modern binaural hearing aids, on the other hand, are able to rotate the microphones in the direction from which the speech signal originates, allowing you to have conversations without having to make eye contact. Effortless hearing is now possible with the latest and advanced hearing devices.
Orientation in a room and problem-free directional hearing essentially requires two healthy ears. The auditory center recognizes the tiniest differences between the incoming signals in the left and right ear, and allocates incoming signals to a position in the room (head shadow effect). Binaural signal processing also makes this possible with hearing aids, therefore enabling you to adequately assess direction. Hearing is also connected with balance so it is important that you wear hearing devices for both ears so your brain is able to understand the surroundings and help you balance.
The cost of hearing devices is hard to approximate as the market has hundreds of different options and the price varies depending on the technology and the features that a particular model has. Some devices are premium level technology with the ability to connect with phones, offering a device chargeability function, tinnitus maskers and they are so small that they can’t be seen. Such devices cost a little more than the basic devices which just help with hearing loss and can be manual rather than digital. Binaural hearing aid are advanced level devices but their quick success has meant that different manufacturers have produced different models, giving people a choice of models and prices.
First time users feel more comfortable with one aid because they are being exposed to sounds that they were missing out on before and can feel overwhelmed when they start experiencing all the different sounds. Also their ear can get uncomfortable with wearing hearing aids, this is because they may be wearing small devices but it is still a foreign object that they have to wear throughout the day to ensure they get used to it. However, audiologists recommend that if you need hearing devices for both ears then you should start off with both devices. Over time, you would become comfortable with the sounds and feel less overwhelmed when the two devices connect to give an overall sound experience and better sound directionality compared to one standalone device.
Welcome to the most powerful brainwave entrainment generator on the web. Don't be fooled by its relatively simple user interface. This software is capable of producing the widest range of brainwave modulations available so far, such as binaural beats, isochronic tones, bilateral entrainment, modulated white noise, and more! If you are eager to start your own brain hacking experiments, the rest of this section covers the basics: the minimum you should know to make sense of the sliders above. If you are interested in further understanding what brainwave entrainment is, more information follows!
Brainwaves are not pseudo-science: they exist. Brainwaves are a by-product of our brain's activity and packs of neurons communicating with each other. These brainwaves fall into different groups, depending on their frequency and their location in the brain. These groups have been linked to various body states, such as being alert, relaxed, or sleepy. Brainwaves are not audible: they are not sound waves, and even if they were, their frequencies would fall way below our audible range.
By using a stimulus at a given frequency, brainwave entrainment aims at synchronizing the brain with that frequency and inducing a given state such as drowsiness or focus. The stimulus could be anything, e.g. visual. This website uses auditory stimuli. Since the brainwave frequencies are not in the audible range, a trick is needed to convert the frequency we want to impose on our brain into something that is audible. The trick consists of selecting a frequency that we hear - we call it a carrier - then modulating this carrier with the brainwave frequency one wants to make audible. This website offers four modulators that can be used separately or combined: amplitude modulation (monaural modulation), binaural beats, stereophonic panning (bilateral modulation) and frequency modulation.
That's it! You can start using our online brainwave tool now. Choose a particular brainwave frequency, a carrier, and then apply some modulation. Tweak the settings until you hit a sweet spot. Let it flow for a couple of minutes at moderate level. Then ask yourself how you feel. Calmer? Focused? Sleepy? Alert? Annoyed by the sound? That is possible too ;-) Everything is possible!
We allow up to five different brainwaves frequencies (1-5) to be mixed together to create complex entrainment routines. If you are new to brainwave entrainment, start using a single brainwave first.
