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.
They are meant to help people without hearing loss hear very quiet noises better (like a hunter listening for a deer) and are not substitutes for hearing aids. These types of devices may, in fact, pose a danger to your hearing by being too loud for your needs. Hearing aids are not only safe, theyâre life-changing.
