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.
Considerations for wearing used hearing aids. There are many factors when trying to decide if used hearing aids might be right for you, including: technology, style, features and fit. The physical fit of the hearing aids can be described according to two basic styles: in-the-ear (ITE) and behind-the-ear (BTE) hearing aids. ITE hearing aids are custom-fit, or made specifically to fit an individualâs ear canal.
