"measure of frequency with which a new case of a specific condition or disease occurs during a specified time period"
A measure of the probability of a disease or an outcome’s occurrence, defined as the number of new cases within a defined time period for a specific population divided by the total number in the population (Gordis, 1996).

The number of newly diagnosed cases for a specific disease or group of diseases during a specific time period, usually a year. When expressed as a rate, it is the number of new cases during that time period per standard unit of population. E.g., 10 cases/100,000 population per year.
In epidemiology, the number of cases of disease, infection, or some other event having their onset during a prescribed period of time in relation to the unit of population in which they occur. Incidence measures morbidity or other events as they happen over a period of time. Examples include the number of accidents occurring in a manufacturing plant during a year in relation to the number of employees in the plant, or the number of cases of mumps occurring in a school during a month in relation to the number of pupils enrolled in the school. It usually refers only to the number of new cases, particularly of chronic diseases. Hospitals also track certain risk management or quality problems with a system called incidence reporting.

The number of new cases of a condition reported during a given period of time, such as the previous year.
Incidence is the number of cases of disease having their onset during a prescribed period of time. It is often expressed as a rate (for example, the incidence of measles per 1,000 children 5-15 years of age during a specified year). Incidence is a measure of morbidity or other events that occur within a specified period of time.

Induction (Loop) ALDs: Employ a magnetic field to transmit the signal from the transmitter to the receiver. The magnetic field is generated by a number of turns of wire forming a large loop (hence the name) attached to a suitable amplifier. The signal input can be either a microphone or an audio feed. The receiver picks up the magnetic field using a tiny coil of wire, converts it into sound and amplifies the sound. Many hearing aids have enclosed within them such coils (T-switch or T-coil equipped hearing aids); in this case the hearing aid is the receiver. ( http://www.alds.com/Lit/AN004A.pdf)

To avoid confusion when using incidence, always indicate the sampling entity and sampling unit in order to ensure clarity. Where the proportion of damaging agent–affected stands or polygons (sampling entity) is of interest in a higher-level sampling unit, use occurrence.

is defined as the frequency of something occurring within a population. More specifically, researchers typically use this term to define the likelihood of finding a particular type of person within a designated sample frame (or sample source). An incidence calculation is used during the fielding process to determine the effectiveness and cost of surveying a target group, and is computed as the Number of Qualified Respondents divided by the Number of Respondents Screened. Note that records that are contacted but not screened (such as a "no answer") are not included in this calculation because it is impossible to know their disposition.
