| hearing loss, partial | A condition in which the sense of hearing, although defective, is functional with or without a hearing aid. The hearing level for speech is approximately 40-70 decibels I.s.o. (international organization for standardization) or 30-60 db a.s.a. (american standards association). (12 Dec 1998) |

| hearing loss, sensorineural | Hearing loss resulting from damage to the sensory mechanism internal from the oval and round windows. (12 Dec 1998) |
| sensorineural hearing loss | <neurology> A form of deafness that occurs due to dysfunction of the auditory nerve (cranial nerve VIII). (27 Sep 1997) |
| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |
| eddy-current loss | <radiobiology> Energy loss due to eddy currents circulating in a resistive material. (09 Oct 1997) |
| tooth loss | The failure to retain teeth as a result of disease or injury. (12 Dec 1998) |
| functional visual loss | An apparent loss of visual acuity or visual field with no substantiating physical signs; often due to a natural concern about visual loss combined with suggestibility and a fear of the worst; best treated with reassurance. (05 Mar 2000) |
