Ear Defenders FAQ's

Q.   What do the letters printed on the Edz Kidz refer to?

A.    The letters printed on the side of the Edz Kidz refer to various international safety standards:

  • ANSI S3.19 - The American National Standards Institute is a private, nonprofit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. Equivalent Australian companies include SAI Global and Standards Australia.
  • S3.19 is the standard introduced by the ANSI to regulate hearing protection devices. Edz Kidz meet these requirements.
  • EN352-1: 1993 - This is the European Standard for hearing protection and hearing protectors, as well as protective clothing and other safety measures. Edz Kidz also meet this standard.

Q.   What ages are the Edz Kidz suitable for?

A.    Edz Kidz can be worn by children of all ages. However, we recommend that they are not used on children less than 6 months old. This is due to the fact that newborns heads are quite soft, and the ear defenders are a reasonably tight fit. PLEASE NOTE: This is a RECOMMENDATION only. We have had customers use Edz Kidz on children less than 6 months, with no problems whatsoever. There is no upper age limit.

Should you find the ear defenders are a bit too tight, they can be stretched slightly. Simply place two chairs back to back, and stretch the ear muffs over the two chairs. After leaving the ear muffs for a while, they will have stretched by a small amount, making them a bit less tight when worn.

Q.   What payment methods do Edz Kidz currently accept?

A.    We currently accept payments via All Major Credit Cards. Credit card payments are directed to our Paypal account and processed through a  secure third party payment gateway. This step by step payment process is 100% secure, and is covered by Verisign's 128 bit SSL Encrypted Secure Transaction program. You do NOT need to be a Paypal member to use this option - one off payments are possible!

Q. Do the ear defenders come in different sizes?

A. Edz Kidz Ear Defenders are a "one size fits all" product. Each side of the ear muffs is adjustable in length. Once placed on the head, each ear covering can be lengthened simply by pulling the ear covering downwards. As a result, EDZ KIDZ ear defenders grow with your child!

Q. What can cause noise-induced hearing loss?  

A. NIHL can be caused by a one-time exposure to an intense  impulse sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a woodworking shop.
The loudness of sound is measured in units called decibels. For example, the humming of a refrigerator is 40 decibels, normal conversation is approximately 60 decibels, and city traffic noise can be 85 decibels. Sources of noise that can cause NIHL include motorcycles, firecrackers, and small firearms, all emitting sounds from 120 to 150 decibels. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the time period before NIHL can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss.
 
Below is a table that outlines different noisy activities and the exposure times until hearing damage.

Who is affected by NIHL?
 
People of all ages, including children, teens, young adults and older people, can develop NIHL. Exposure occurs in the workplace, in recreational settings and at home. Recreational activities that can put someone at risk of NIHL include target shooting and hunting, woodworking, listening to or playing loud music and other hobbies. Harmful noises at home can come from music, lawnmowers, leafblowers and other power tools.
 
Can NIHL be prevented?
 
NIHL is 100 percent preventable. All individuals should understand the hazards of noise and how to practice good hearing health in everyday life. To protect your hearing:
Know which noises can cause damage (those at or above 85 decibels).
Wear earplugs or other hearing protective devices when involved in a loud activity
Be alert to hazardous noise in the environment.
Protect the ears of children who are too young to protect their own.
Make family, friends, and colleagues aware of the hazards of noise.
If you suspect hearing loss, have a medical examination by an otolaryngologist (a physician who specializes in diseases of the ears, nose, throat, head, and neck) and a hearing test by an audiologist (a health professional trained to measure and help individuals deal with hearing loss).
