What Are the Sign of Hearing loss and How to Avoid While Using Ipods/Iphones?
Digital audio players (are easy to carry and can store a lot of music, so their rise in popularity adds new concerns about listening to high sound levels for long periods of time. Research data from hearing specialists shows that the number of young people who show signs of hearing loss is increasing. All combinations of headphones/earphones and CD players and DAPs could generate potentially harmful sound levels.
Before we want discuss hearing loss let us see first how this sound level is measeured. Scientists measure the levels of different sounds with a unit called the decibel (dBA).
Healthy Sound Level
Research shows that sounds with levels below 70 dBA pose no known risk of hearing loss, no matter how long they last. A sound level of 70 dBA is about what you would experience while driving alone in a family car at highway speeds with the windows closed and the radio off.
If you listen to music at levels higher than 70 dBA, the amount of time you spend doing so becomes an important factor. For example, listening to music at 85 dBA for 45 minutes a day poses no known risk of hearing loss. On the other hand, listening at that level (or higher) for 8 hours a day can pose a significant risk of hearing loss.
If people around you can hear your music right through your ear phones, your tunes are too loud.
Sign of Hearing loss
If you experience early signs of hearing loss, you should contact your doctor's office to discuss the need for a test or examination. Early signs include:
- When an ongoing noise stops, sound may seem muffled
- Your ears ring
- People tell you the TV is too loud
- You keep turning up the stereo so you can hear it
- You feel pressure or fullness in your ears.
- Difficulty trying to follow a conversation in the midst of background sounds (e.g. at a social gathering or in a cafeteria).
- The perception that people around you are mumbling.
- Hearing a ringing, buzzing, roaring, or rushing sound in your ear when there is nothing making these sounds. This condition is called tinnitus
Minimizing Your Risk
Here are some tips to reduce the risk of noise-induced hearing loss from personal stereo systems:
- Keep the sound at enjoyable, but safe levels. If someone a metre away must shout to be understood, the sound level of the music is probably higher than 85 dBA, and may be hazardous.
- Use various system controls to increase enjoyment while decreasing your risks. For example, you could turn down the volume and increase the bass boost. You could also use a feature that is available on many MP3 players to reduce volume differences between songs. Names for this type of feature range from the more general term "Replay Gain (RG)" to "Sound Check" on the iPOD.
- Limit the amount of time you spend listening to loud music in your IPOD ansd Iphones
- If possible, reduce background noise so you can use a lower volume level.
- Other Safety Concerns-There is more at stake than your hearing. Excessive sound levels can create dangerous situations. If your personal stereo system is so loud that you cannot hear sounds around you, such as traffic, your personal safety may be at risk.
- Also, if you use noise-reducing headphones to reduce background noise, be aware that it is not safe to tune these sounds out when you are walking or cycling along a busy street, because you need to be aware of what is going on around you.
- It's a good idea to pre-set the volume on electronic music devices to between half and two-thirds of maximum
