Tips For Musicians to Help Protect Your Hearing

!±8± Tips For Musicians to Help Protect Your Hearing

One thing many musicians fail to think about when they start off on their musical journey is how to properly protect their hearing. Although your instrument will bring you countless hours of inexplicable joy, if you are not careful, it will bring you a lifetime of hearing damage.

OSHA regulations state that the threshold for db level in the workplace is to be no more than 90db for a maximum of 8 hours. Here is a quick breakdown of acceptable db levels per hour.

90 dbA 8 hrs
92 dbA 6 hrs
95 dbA 4 hrs
97 dbA 3 hrs
100 dbA 2 hrs
102 dbA 1.5 hrs
105 dbA 1 hr
110 dbA 0.5 hr
115 dbA 0.25 hr or less

You may be wondering exactly how loud 90 db's is. This is the level of a common home lawnmower. Imagine how loud your new instrument is when you really get going. Actually, you don't need to; here is a chart for that as well.

60-70 dB normal piano practice
70 dB fortissimo singer 3 ft. away
75-85 dB chamber music in small auditorium
84-103 dB violin
85-111 dB flute
85-114 dB trombone
106 dB timpani & bass drum rolls
120 - 137 dB symphonic music peak
150 dB rock music peak

So now what? Well, the good news is you have the capability to completely protect yourself. The best way to prevent any hearing loss is to always use ear plugs, even when you are just practicing, even when you are just practicing by yourself.

When looking for ear plugs, one thing you want to look for is the NRR which stands for Noise Reduction Rating. This is pretty self explanatory and is easy to figure out, the higher the NRR, the more noise it will keep out. Here are a few common ear plugs on the market today.

INDUSTRIAL FOAM: These are the bright yellow or orange foam ear plugs you can find almost anywhere. The plus to these is that they are one of the best at simply blocking out all the noise and they are super cheap as well as easy to find. The draw back to these is since they block out all frequencies, you will tend to get a very muffled sound. This could be tough to handle in a band setting when you are listening for cues from your band mates, or simply wanting to enjoy your musical experience a little more.

EAR PLUGS: These are the ones that look like Christmas trees. They are rubbery with 3 ridges and a tail piece to make it easy to get them in and out of your ear. They do not block as many frequencies as the foam ones which means there is a less muffled sound coming through. These come in at a price of around .

CUSTOM MADE: These are the ultimate for any musician. These will cut out most, if not all of the damaging frequencies. These result in the ultimate experience of clarity while still offering maximum protection. The down side of these is that they ain't cheap! These will cost you around 0, but compared to hearing aids later on, this is a bargain. Also, you can't pick these up just anywhere. You will need to go to an audiologist to get fitted for a pair. The plus is that these will be much more comfortable than the generic ones. This comes in handy when your are doing a long rehearsal or show.

In the absolute worst case scenario, the old standby of cotton or toilet paper will do the job decently. This should not be your standard operating procedure though.

One last tip, which ever set you decide is right for you, make them easily accessible. Most musicians carry their plugs in a gig bag, instrument case, a lanyard around their neck, or even a key chain. Which ever way is easiest for you, do it. Keep them close; it is way to tempting to just start jamming if getting to them is going to be a hassle.

If you follow this advice, you will have a long, healthy future ahead of you with many years of musical enjoyment.

The Importance Of Aviation Headsets In Flight Training

!±8± The Importance Of Aviation Headsets In Flight Training

Pilot headphones are valuable tools in general aviation (GA) cockpits. Besides blocking unwanted sound, earphones facilitate internal & external communication while reducing noise-related fatigue. Though great for all types of flying, earsets are particularly valuable in flight training operations.

For those new to aviation, a general aviation cockpit presents several challenges. Rookie aviators often have little or no experience flying in light aircraft. An effective way to improve their experiences and simplify their flight training is by using aviation headsets.

One of the primary benefits of pilot headphones is hearing protection. The Occupational Safety and Health Administration (OSHA) cites 85 decibels as a "safe" daily exposure amount for a period of up to eight hours. Above this noise level, OSHA notes that even short periods of exposure to loud noise can result in permanent hearing loss. Some individuals are susceptible to detrimental hearing damage at noise levels below 85 decibels. General aviation aircraft, particularly high-performance models, can generate noise in excess of 100 dB (A) at high power settings. To protect aviation students from possible hearing damage, earphones should be used for all flight lessons.

Another benefit of a pilot earset is the increased level of comfort it provides students. With limited general aviation experience, light aircraft cockpits can be overwhelming places. Loud noises, numerous strange controls & gauges, perplexing radio calls, and low-level turbulence can easily cause nausea, fatigue, and even fear. By blocking unwanted engine noise, earphones can greatly reduce any discomfort or fatigue a student might experience. Eliminating these undesirable factors increases the chances student pilots will continue their flight training. In addition, when used with a push-to-talk (PTT) switch, headphones remove the students' need to fumble with a hand microphone for external communications.

Perhaps the greatest advantage of GA headphones is the ease of communication they provide to flight students. Communication is one of the three vital pilot responsibilities a student must master. The phonetic alphabet, radio procedures & phraseology, and required communications reports are daunting tasks for those new to aviation. In addition, rookie pilots must learn to identify navaids, listen to weather broadcasts, and contact flight service stations & FBOs. The sheer volume of required communication makes proper correspondence a crucial task for new pilots. These responsibilities become even more important in the instrument flight (IFR) environment. Besides these required external communications, flight training students must also maintain constant contact with their flight instructors throughout the course of each lesson. Imagine trying to learn by shouting back and forth over loud engine noise. By adding a headset, a pilot's communication duties become much easier to perform.

Unlike many other disciplines, flight training requires constant communication in a high-noise environment. Improper transmission or reception of required information can have devastating effects on the safety of a flight. By reducing unwanted noise and facilitating clear communication, student pilots stand a better chance of successfully completing their flight training. Aviation headsets. are valuable tools to assist in making that happen.

The OSHA 30 training course presents several advanced sections regarding workplace safety. Some areas covered in the program include the safe use of motor vehicles at a worksite. Identifying and safely handling lead at a worksite and fire protection. Supervisors and foremen are also trained in proper recordkeeping and completion of all required forms and paperwork relating to workplace safety. Proper procedures for the handling and disposal of hazardous materials, including asbestos are discussed in one course module. Special attention is given to certain hazardous activities that may cause injury.

A standard 30-hour curriculum for construction trades workers will include safety around excavations and tunnels and the safe use of explosives at a worksite. These are all extra hazardous situations that require heightened attention. Time is spent in keeping records of hazardous situations and accounting for all tools and explosives used. Inventory control and reporting is also taught. All students also learn about required safety equipment at a workplace.

From the use of safety goggles and steel toed shoes to proper harnessing at heights is discussed in an OSHA 30 training curriculum. All workers are educated about the necessities of taking precautions to protect themselves from hearing loss and impaired vision from workplace hazards.

The OSHA 30 training course provides a comprehensive education into OSHA regulations as they pertain to construction worksites. Persons completing the course will be able to identify, remediate and report any hazardous situation. All courses will meet the requirements of Department of Labor continuing education.
