noise

 I have never had someone who had given me a headache just by merely uttering words. In fact, I have never had a friend who is as loud as me that had made me loose my thoughts because of severe headache.

I had this colleague, who graduated at the same school that I have studied at, when I was in college. We were just "cliche friends" before, because he was a year younger than me. Until, we became colleagues and had work at the same unit. His loudness has come to my knowledge through word of mouth, it only came to a bitter realization that his loudness was indeed a cry of deadly-wrath when we had a back-to-back duty.

At first, everything was tolerable. I could even endure the volume and tone of his voice that was slowly gnawing my tympanic membrane, it was a loud shrill, yet tolerable. Up until I can’t merely decipher things that are getting into my auditory sense. All I can hear are mere mumbles but are annoying buzzes that almost made me puke. At that point I thought the ossicles in my inner ear could not quite coordinate because of the noise pollution that it’s facing.

"yada.. yada.. yada.." "balahura" "blah" blah" "buzzzzzzZzzz…." imagine that on a low tone but loud voice, plus imagine that being uttered by a number of people and I bet you’d go nuts. Even the strongest pain reliever can’t relieve you of the damage it has caused.

In relation to this, I’ve learned that noise is defined as complex sound waves that are aperiodic, in other words, sound waves with irregular vibrations and no definite pitch. Noise in our environment affects physical heath. Noise also has psychological and social implications and affects our well being and quality of life. In addition, noise not only affects hearing. It affects other parts of the body and body systems. It is now known that noise: (1)Increases blood pressure (2)Has negative cardiovascular effects such as changing the way the heart beats (3)Increases breathing rate (4) Disturbs digestion (5) Can cause an upset stomach or ulcer (6)Can negatively impact a developing fetus, perhaps contributing to premature birth (7) Makes sleeping difficult, even after the noise stops   and (8) Intensifies the effects of factors like drugs, alcohol, aging and carbon monoxide.

Both the amount of noise and the length of time you are exposed to the noise determine its ability to damage your hearing. Noise levels are measured in decibels (dB). The higher the decibel level, the louder the noise. Sounds louder than 80 decibels are considered potentially hazardous. The noise chart below gives an idea of average decibel levels for everyday sounds around you:

Painful

150 dB = rock music peak

             = ROGELIO RAFAEL DAJAO (te paeng.. love U)

140 dB = firearms, air raid siren, jet engine

130 dB = jackhammer

120 dB = jet plane take-off, amplified rock music at 4-6 ft., car stereo, band practice

Extremely Loud

110 dB = rock music, model airplane

106 dB = timpani and bass drum rolls

100 dB = snowmobile, chain saw, pneumatic drill

90 dB = lawnmower, shop tools, truck traffic, subway

Very Loud

80 dB = alarm clock, busy street

70 dB = busy traffic, vacuum cleaner

60 dB = conversation, dishwasher

Moderate

50 dB = moderate rainfall

40 dB = quiet room

Faint

30 dB = whisper, quiet library

On the other hand, if you think you have "gotten used to" the noise you are routinely exposed to, then most likely you have already suffered damage and have acquired a permanent hearing loss. Don’t be fooled by thinking your ears are "tough" or that you have the ability to "tune it out"! Noise induced hearing loss is usually gradual and painless, but, unfortunately, permanent. Once destroyed, the hearing nerve and its sensory nerve cells do not regenerate! 

Lastly, protect Yourself from "Noise." The key word in dealing with noise is prevention! We want to eliminate unwanted noise when we can. When noise cannot be eliminated, we want to keep it as low as possible. Here are some things to do:

• Wear hearing protectors when exposed to any loud or potentially damaging noise at work, in the community (heavy traffic, rock concerts, hunting, etc.) or at home (mowing the lawn, snow blowing the driveway, etc.). Cotton in your ears won’t work. Hearing protectors include ear muffs and ear plugs (not swimmer’s plugs), some that are custom-made and individually molded. This protection can be purchased at drug stores, sporting goods stores or can be custom-made. Check with your audiologist to find out what best suits you.
• Limit periods of exposure to noise. Don’t sit next to the speakers at concerts, discos, or auditoriums. If you are at a rock concert, walk out for awhile give your ears a break ! If you are a musician, wear ear protection–it is a necessity! Take personal responsibility for your hearing.
• Pump down the volume! When using stereo headsets or listening to amplified music in a confined place like a car, turn down the volume. Remember: if a friend can hear the music from your headset when standing three feet away, the volume is definitely too high. Don’t be afraid to ask others to turn down the volume.
• Educate yourself about the damaging effects of noise and what you can do to prevent your exposure to noise.
• Educate others and take action! Educate your children through discussion and by example. Wear your ear protection and encourage your children to follow your example. Provide them with ear protection. Remind them to turn down stereo headsets. A rule of thumb is that, if sound from a head set can be heard by others 3 feet away, it is too loud.
• Be a responsible consumer. Look for a noise rating when buying recreational equipment, children’s toys, household appliances, and power tools. Choose quieter models, especially for equipment that you use often or close to your ears like a hair dryer. If there is no noise rating, contact the manufacturer and ask for one!
• Inspect your child’s toys for noise danger just as you do for small parts that can cause choking. Remember, too, that children tend to hold toys close to their ear which can pose additional threat for hearing damage.
• Have your hearing tested by an audiologist certified by the American Speech-Language-Hearing Association (ASHA), especially if you are concerned about possible hearing loss. Remember the warning signs of over exposure to noise.
• Be aware of the noise in your environment and take control of it when you can. Be an advocate for reducing noise pollution. Your county may have a local noise ordinance. Find out what you can do in your community to advocate for quiet. For example, some schools have set a decibel limit for the music played at school dances in order to protect the students’ hearing.
• Be an advocate! Remember there are no regulations governing how loud sound can be in public places such as discos, movie theaters, dance clubs, exercise centers. Work with owners, managers, and community leaders to create a healthier less noxious listening environment.
