Benefits and Harmful Effects
Have you ever noticed how dramatically music can affect your mood? If you are lacking in energy, turning up the volume to your favorite upbeat song, can give you a natural shot of adrenalin. Fast music can actually change your brainwave s , making you more attentive, alert, and observant. If you’re feeling nervous or agitated, slow music can make you calm and relaxed, as it slows down your breathing and heart rate. It’s a good way to lessen anxiety and to promote a feeling of peacefulness. Music can boost creativity, and lift the spirit. Classical music has even been found to aid in digestion and to reduce a certain stress hormone, known as cortisol. Music can also be a sleep aid at the end of a stressful and long day, when our bodies are tense and exhausted.
The introduction of music therapy into the health field has been an exciting endeavor. Hospitals often use music therapy to calm patients, to control pain, to alleviate depression, and to relax muscles. Music therapy has also provided help to cancer patients, and children struggling with ADD (Attention Deficit Disorder). Music seems to be a natural drug, able to lower blood pressure and increase the immune response. Music therapy promotes healing after surgery, and is also helpful in relieving despondency in the elderly, who are shut-ins. Listening to music for just one hour a day, can help with chronic pain control and can even help with the reduction of pain medications. Many women are using relaxing music therapy as an aid during labor and delivery.
Memory and Music
According to researchers at the University of Wales Institute, any music heard while trying to concentrate can be distracting and impair the ability to memorize and recall information down the volume to LESS than 85 decibels (comparable to a busy restaurant).
This conclusion was reached after 25 people were asked to recall information while in a quiet environment and again while music was playing that the participants both liked and disliked. The study participants all performed better in the noiseless environment, leading one researcher to conclude that people should either perform tasks in quiet or listen to music prior to performing a task, not during the task.
When I hear loud music through earphones or headphone it feels like I have great amount of energy but after listening my mental efficiency is decreased and I feel irritated and mentally tired.
The louder the music, the larger the vibration of the eardrum, and the stronger the impulse sent to the brain. The reason you are feeling the way you do is your body is telling you that harm is being done to the eardrum (danger of rupture). The best way to avoid any permanent damage – which it seems is going to happen any time now is to turn down the volume to LESS than 85 decibels (comparable to a busy restaurant). Check the link below to see other possible and probable side effects of loud music.
Portable music players may be contributing to permanent hearing loss among many casual listeners, gradually leading to the inability to discern speech. An iPod’s maximum volume is more than 10 times as loud as the recommended listening setting, audiologists say that the sensory damage caused by prolonged listening is irreversible. Hearing damage from loud music is not always permanent, but prolonged exposure to loud noise can lead to health problems such as hypertension and tinnitus, or ringing in the ears.
Noise-induced hearing loss occurs, simply, when sensitive cells in the inner ear are exposed to loud noises. These “hair cells,” which convert sound energy into electrical impulses that are sent to the brain, can’t grow back once they are damaged.
HOW MUCH IS TOO MUCH?
Occupational Health and Safety regulations have been established for heavy industry workers who are exposed to noise in their jobs. In the absence of any other rule, and because our ears don’t distinguish between ‘work noise’ and ‘having a good time noise’, this is how we determine safe levels of exposure to music.
- Don’t Listen So Loud – Most researchers agree that it’s safe to regularly listen to your iPod at about 70% of its maximum volume. Anything louder than that over an extended period is risky.
- Use Volume Control –In response to consumer concerns, Apple offers a volume limit setting for some iPods. If your iPod support this, you’ll generally find it on the main iPod management screen that comes up when you sync. Otherwise, you can also restrict the maximum volume of a song in “options” tab of any song in iTunes.
- Limit Your Listening – The length of time you listen, not just the volume, can contribute to hearing loss. The louder the music, the shorter you can listen but giving your ears a chance to rest between sessions will help them heal.
- Use the 60/60 Rule – Since the combination of volume and length of exposure can cause hearing loss, researchers recommend applying the 60/60 rule: listen to an iPod for 60 minutes at 60% of max volume and then take a break. Ears that get a rest have time to recover and are less likely to be damaged.
- Don’t Use Earbuds – Despite them being included with every iPod and iPhone, researchers caution against using Apple’s earbuds (or those from other manufacturers). Earbuds are more likely to cause hearing damage than headphones that sit over the ear and they can also be up to 9 db louder than over the- ear headphones (not such a big deal when you’re going from 50 to 60 db, but much more serious going from 70 to 80).
- Use Noise Dampening of Cancelling Headphones – The noise around us can contribute to cause us to change how we listen to an iPod. If there’s a lot of noise nearby, it’s likely that we’ll turn up the iPod’s volume, thus increasing the chances of hearing loss. To cut down on, or eliminate, ambient noise, use noise-deadening or –cancelling headphones. They’re more expensive, but your ears will thank you.
- Never Max It Out – Though it’s easy to find yourself listening to your iPod at max volume, try to avoid this at all costs. Researchers advise that it’s safe to listen to your iPod at maximum volume for just 5 minutes.
