CLSI recently gave its users some good advice in response to system operators' complaints that they cannot hear well when using the telephone because of the noise level in the area near their systems. Users of other systems may find the suggestions useful.
The simplest device, says CLSI, is a rubber ear-cup available from most stationary stores. Designed as a cushion, this cup actually cuts out environmental noise and is available at a low cost. Another alternative, available from the telephone company, involves a volume control on the telephone handset. This control may be adjusted to individual comfort or need and is the one in use at CLSI. The local telephone company can provide availability and monthly rental information. A third alternative is a telephone amplifier for the hearing impaired. These are normally available at local RADIO SHACK or other electronic supply stores and have the benefit of a one-time cost rather than a monthly rental charge.
