The Real Sounds Of Hearing Loss

The Real Sounds Of Hearing Loss | Sound Engineering- Aspects 2&3 | Scoop.it
For the hearing-impaired, sounds are quieter, but they can also be fuzzier and maddeningly distorted. Listen to these audio clip simulations of what that kind of hearing loss sounds like.

(Aspect 3) 9. They describe how easy it is to fix vision by the use of glasses or contacts, and the difficulty of fixing hearing to the same standards. Hearing loss can mean more than just losing your hearing. Plenty of hearing impaired individuals have to deal with annoying muffled, and fuzzy voices. There are various clips, all saying the same message, but with different hearing impairments. This really shows the struggle of everyday life for the hearing impaired and the help that hearing aids could bring to them.

(Aspect 3) 10. Many people who suffer hearing loss explain that inaudible sounds will abruptly become painfully loud to them. Hearing aids are able to fix this problem called "recruitment" by using "amplitude compression". This means that the ear piece will decrease the volume of loud noises before they get to the patients ear.

This is a quick read with great audio examples pointing out what hearing loss at frequency levels.

To Make Hearing Aids Affordable, Firm Turns On Bluetooth

To Make Hearing Aids Affordable, Firm Turns On Bluetooth | Sound Engineering- Aspects 2&3 | Scoop.it
Traditional hearing aids can be too expensive for many people. But a new type that uses Bluetooth technology costs only about $300. The company that makes the new devices aims to reach millions of people around the world who need hearing aids but have trouble paying for them.

(Aspect 3) 4. One deaf patient was describing how it is embarrassing to have this impairment. He said its terrible when you cannot understand what people are saying around you, so you just smile and nod your head like an idiot, but you don't know if what they are saying is good or bad. This patient tested one of the prototype devices and is very impressed with the adjustability of the device.

(Aspect 3) 5. Another obstacle for obtaining hearing aids is the amount of doctor visits needed to adjust the device. This problem is solved by implementing bluetooth technology in order to adjust the aid. They do this by creating an app that provides a hearing test using a device resembling a bluetooth headset. It then adjusts the device for you by compensating for the users hearing loss.
lexie perez's comment, March 24, 2014 11:16 AM
(Aspect 3) 6. The device does not require the app to turn it on or off because their are set presets on the device if it is already adjusted. The device can be mailed to you and all the user has to do is get the app for the device and program and adjust it themselves. Which is a really good alternative to going to numerous doctors visits in order to adjust the device, and also paying almost 10 times more.

4. They discuss a proposed federal mandate that forces all new vehicles produced to have a back-up camera. This mandate has been pushed back to 2016 or even later. This mandate will open a much bigger market of cameras, monitors, and sensors which could open multiple employment opportunities.

5. Another integration that is becoming a major part of the automotive audio business is connecting vehicles with the owners smart phones. As smart phones keep evolving, so will this industry of trying to connect them faster, and easier into the vehicle. There are also new innovations that are suggesting being able to access news and other information from your dashboard, which will drive the growing industry.

6. They explain the demographics for this type of technology is all over the place. For example, the demographic looking for bumping sound systems and flashy cars is about 18-30 years old. While the demographic for safety and comfortability is the 30-70 range. However, these demographics are all included in front seat entertainment, which is used everyday. Knowing this information, its obvious this industry is just growing and also reaches out to a lot of different age groups.

10. In this article, he describes 'user based design'. This means they are addressing subjective human factors to improve the man/machine interaction. This is not only capable of radically changing audio product designs, but creates the need for a new approach to the research and design process.

New findings on how the ear hears could lead to better hearing aids

New findings on how the ear hears could lead to better hearing aids | Sound Engineering- Aspects 2&3 | Scoop.it
A healthy ear is much better at detecting and transmitting sound than even the most advanced hearing aid. But now researchers reporting in the August 20 issue of the Biophysical Journal, a Cell Press publication, have uncovered new insights into how the ear—in particular, the cochlea—processes and ...

(Aspect 3) 7. A new expiriment by researchers for Biophysical Journal has released new insight into the human ear that could help in the development of hearing aids. They explain that a healthy human ear is better at detecting and transmitting sound than the most advanced hearing aid. However, they have discovered special sound gathering cells in the ear called "hair cells".
lexie perez's comment, March 24, 2014 11:28 AM
(Aspect 3) 8. These sound-sensing cells within the cochlea, vibrate strongly at different frequencies. In order to examine this process, researchers placed tiny censors that measured small pressure fluctuations in the ear. They examined that the vibrations actually open a channel for the sound to go through and be transmitted to your brain.

1. The first commercial in-car radio was introduced by the Galvin brothers in the 1930's. It evolved to the first eight track tape player in 1963, and again evolved to the first in-car CD player in 1985. So there is no doubt that the growth of this industry has slowed down, but it is still growing none the less.

2. Multiple innovators have contributed to the growth of automotive audio. The industry will need more innovators in the future to continue to sprout new ideas and products. Automotive audio is certainly not going away, so new leaders and innovators need to be introduced to the industry.

7. The article shows various audio products for sale for various uses. One direction for audio is marine audio, or speakers for a boat or aquatic vehicle that is exposed to water. This just shows how many directions getting into the field of audio could take me.

8. They are seamlessly integrating smartphone technology into automotive stereo products such as pioneer. If you have a pioneer system installed, you can download an app on your smartphone to connect to the system. All of this technology is also brought to the vehicle through a large touch display screen.

9. Another apparent technology in vehicles is the drop down monitor. These monitors need audio that matches the intensity of what is being shown on them. So developments are being made to provide the best quality sound possible, these jobs seem strong for the future.
