MSMA (monosodium methanearsonate) is an arsenic-based grass killer. It kills grassy weeds such as crabgrass and goosegrass without harming most turfgrasses. It contains organic arsenic that, according to the University of Tennessee Extension, is less harmful than aspirin.
There are several styles of hearing aids available, from the smallest - Invisible in the Canal (IIC) to the largest and strongest - Power Behind the Ear (BTE), and the very popular Receiver in the Canal (RIC) - made to fit most hearing losses while remaining nearly unseen.
Hearing aids are tiny instruments you wear in or behind your ear. They make sounds louder. Things sound different when you wear a hearing aid, but your hearing healthcare professional can help you get used to it. To find the hearing aid that works best for you, you may have to try more than one. Ask your hearing healthcare professional whether you can have a trial period with a few different hearing aids.
