Assistive Listening Device: From 1 Different Sources


a device for helping people with hearing difficulties. An assistive listening device can be a stand-alone device or can work in conjunction with a *hearing aid or *cochlear implant. Assistive listening devices include *induction loop systems, amplifiers for telephones, and radio headphones to wear when listening to the radio or television. Such devices increase the loudness of the desired sound without increasing the level of any background noise; i.e. they improve the signal-to-noise ratio. See also environmental hearing aid.

Intrauterine Contraceptive Device (iucd)

A mechanical device, commonly a coil, inserted into the UTERUS to prevent CONCEPTION, probably by interfering with the implantation of the EMBRYO. For many women, IUCDs are an e?ective and acceptable form of contraception, although only about 10 per cent of women in the UK use them. The devices are of various shapes and made of plastic or copper; most have a string that passes through the cervix and rests in the vagina.

About one-third of women have adverse effects as the result of IUCD use: common ones are backache and heavy menstrual bleeding (see MENSTRUATION). The frequency of unwanted pregnancies is about 2 per 100 women-years of use. (See CONTRACEPTION.)... intrauterine contraceptive device (iucd)
