One of the most important reasons why we see so many different hearing aids types is the fact that hearing loss is different from one person to the other. Out of all hearing aids types the one that gained the most popularity recently is the digital hearing aid. We also have body aids, which are of great help for the individuals that cannot physically use an ordinary hearing kit.
The bottom line is that it can be really complicated to realize what the different hearing aids types can do for you. There are two main reasons a person would want to limit both the range of frequencies and the level of amplitude or loudness when creating and listening to music.
This fact made it necessary to develop different devices that will help people with different hearing impairments. Alternatively one can also use ITC (in the canal) hearing aids, which are cosmetically great looking and are almost invisible due to positioning. It is placed right under the skin and the problem is that most people think they are cochlear implants. You will need to research all the possibilities available and focus on your hearing problem, style wanted and budget in order to make the best move possible. This foundation teaches us that there are specific limitations to consider when listening to music, making music, working in loud environments or when around or exposed to extremely loud noises over a protracted period of time.The second consideration regarding audible range of human hearing and the influence of loud sounds is for understanding that there are limitations to our human ability to hear all sounds and noises.
Nowadays this changed as hearing aids have been developed and can help out most people that suffer from all levels of hearing loss. We thus have hearing aids that are programmable and fully customizable on the basis of personal audiogram. These gadgets have all the functionalities of regular hearing aids but they can also monitor the audio environment surrounding people.
In fact, the new body aids that are available are much smaller than before and are more similar to the modern ones in terms of technology and aesthetics.
It is in understanding this limitation that we know we do not hear the complete sound spectrum, only that a portion of the sound spectrum falls into the audible range of human hearing.Audible Range of Human Hearing a€“ The average person has a normal hearing range that falls between 20Hz on the low side and approximately 20,000 Hz on the high side. They are perfect for most people because they are perfectly designed for those that are suffering from a hearing problem type.


We even have different shell styles for the hearing aid types like hard, soft, low profile, half or full.
The implantable hearing aid is basically a regular hearing aid but it is surgically inserted. As we age the overall perceivable range of sound decreases especially in the higher frequencies. There are different hearing aids types on the market and you can easily become confused with what you should be purchasing.
Most hearing aids types on the market are good for those that suffer from mild to moderate problems. In the event that a person is faced with severe and advanced hearing loss we are faced with just a few options that are available. Our capability to hear sounds in the upper portion of the audible range of human hearing are for most people the first to go, as far as hearing loss is concerned.The video below will give you a first hand experience of the limits of your own hearing capability.
This just happens to be one of the better test examples especially in the upper frequency range where you can more closely identify the frequency at which you are unable to hear the sound. When you cannot hear the sound any more, this is your upper limit within the sound spectrum.Caution a€“ Please listen to this video with caution by setting your speaker or headphone volume to normal hearing levels for you.
You may want to make adjustments as the video progresses so please keep your fingers on the volume control to protect your hearing. Most people never come to the realization that our own bodies limit our experiences of the universe and its limitless capabilities. Loud sounds that are near 85dB can begin to cause hearing loss if experienced over prolonged periods of time.Due to the risks to the delicate nature of the tiny tissues and structures within the physical ear, those that make it possible for us to hear, we must do everything possible to limit long term exposure to loud noise and loud music in order to protect them. I would strongly urge that you wear hearing protection if you are exposed to loud sounds regularly.
Also, listening to music within your comfort zone makes more sense than risking irreversible hearing loss thus limiting our own audible range of human hearing.Loudness or amplitude is measured in decibels and it is marked or notated using dB to designate decibels. This is why after attending a concert your ears may ring or take a while to settle down afterward.In reality, it is never a good idea to listen to extremely loud music for long periods of time without some sort of hearing protection. The consequences can be negative due to the sensitivities of the structures in our physical ear.


It is by far more beneficial to limit the amplitude or loudness of the sounds we experience to within normal hearing ranges as much as possible, to limit the potential damage that may occur when listening to extremely loud sounds or music on a frequent basis. Frequency Limitations a€“ Below is a chart comparing the range capabilities if various worldly creatures.
The audible range of human hearing versus that of other living creatures is an interesting study. This limitation is caused first by purely biological reasons and secondly by the damage caused by exposure to loud sounds. The chart includes the maximum range of audible and perceptible sound each species included in the chart is capable of hearing including the human species.Frequency is measured using the Hz symbol meaning Hertz.
Noting that the limitation of the range of human hearing is between 20 Hz and 20,000 Hz one can easily see that frequencies exist outside of our capability to hear them.
With that said, it is far more useful to write music within the audible range of human hearing. WE must always keep in mind the keeping the maximum amplitude limited to prevent hearing loss and to limited by choice the number of frequencies to only those frequencies which comprise the universally accepted frequency range of sound, as used in music and music composition and those that fall into the audible range of human hearing.
It is therefore useful and appropriate to study the concept of acoustics and more specifically the concepts of frequency and amplitude as they are an underlying set of principals which are part of and necessary for completing your understanding of the components of another useful system herein called the musical scale.Part 3 of the series Acoustics of Music included in the overall series Scales in Music a€“ A Tonal System will provide some important information about acoustics and one of the key underlying principals in acoustics and the characteristics of sound.
The concept is called frequency.Please proceed with your reading of Part 3 which begins looking into these ideas about frequencies. The American Tinnitus Association – is another very excellent resource for those who may be suffering from this health condition.
Hopefully they will prove helpful to you as you visit this Music Theory and Composition website.
