Large Area Listening Systems. Large area listening systems are the most popular of all hearing enhancement devices, and are used in theaters, movie houses, auditoriums and houses of worship. There are three basic types: FM radio, infra-red (IR) light and a looped wire around the room, called an induction loop.
The strings are called Phloem Bundles (pronounced flom). They are part of the system that carries nutrition to all parts of the banana.
Individual banana fruits (commonly known as a banana or finger) average 125 grams (0.276 lb), of which approximately 75% is water and 25% dry matter (nutrient table, lower right). The fruit has been described as a leathery berry.
