Runny eyes. Sneezing. Nasal discharge. Loss of appetite. Shelter workers all know the signs. Feline upper respiratory infections (URI for short) are the most commonly encountered disease problem in animal shelters. Some shelters have cases all the time. Others have outbreaks that can only be referred to as epidemics that result in the suspension of feline adoptions.
Low-Tech Assistive Listening Devices Still Boost Hearing. Every amplifying device has three parts - a microphone, a mechanism to amplify sounds picked up, and a speaker that alters the sound and transmits it to you, Loavenbruck explains. While traditional hardwired assistive listening devices are still popular and inexpensive, wireless technology is getting the biggest buzz.
In these cases, you may want to consider trying an Assistive Listening Device or ALD. Hearing devices can be used to overcome the effects of background noise, poor room acoustics or far distance from the speaker. And for people who are hard of hearing, an assisted listening device may be used with or without a hearing aid.
