they have wireless phone shielding, and whether your hearing aid has a HAC rating.

7.5 FDA CONSUMER UPDATE
U.S. FOOD AND DRUG ADMINISTRATION CENTER FOR
DEVICES AND RADIOLOGICAL HEALTH CONSUMER UPDATE ON
WIRELESS PHONES
1. Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health problems are associated
with using wireless phones. There is no proof, however, that wireless phones are
absolutely safe. Wireless phones emit low levels of radiofrequency energy (RF) in the
microwave range while being used. They also emit very low levels of RF when in the
stand‐by mode. Whereas high levels of RF can produce health effects (by heating tissue),
exposure to low level RF that does not produce heating effects causes no known
adverse health effects. Many studies of low level RF exposures have not found any
biological effects. Some studies have suggested that some biological effects may occur,
but such findings have not been confirmed by additional research. In some cases, other
researchers have had difficulty in reproducing those studies, or in determining the
reasons for inconsistent results.
2. What is FDA's role concerning the safety of wireless phones?
Under the law, FDA does not review the safety of radiation‐emitting consumer products
such as wireless phones before they can be sold, as it does with new drugs or medical
devices. However, the agency has authority to take action if wireless phones are shown
to emit radiofrequency energy (RF) at a level that is hazardous to the user. In such a
case, FDA could require the manufacturers of wireless phones to notify users of the
health hazard and to repair, replace or recall the phones so that the hazard no longer
exists. Although the existing scientific data do not justify FDA regulatory actions, FDA
has urged the wireless phone industry to take a number of steps, including the
following:
• Support needed research into possible biological effects of RF of the type
