A noise-figure meter could automate that procedure as follows: A gated broadband noise source (such as an avalanche diode) drives the device under test. A measurement is made with the noise source on; another measurement with the noise source off. From those measurements and the characteristics of the noise source, the noise figure can be ...
The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is an intelligence test designed for children ages 2 years 6 months to 7 years 7 months developed by David Wechsler in 1967. It is a descendant of the earlier Wechsler Adult Intelligence Scale and the Wechsler Intelligence Scale for Children tests. Since its original publication ...
AB 484, introduced on September 4, 2013 in the state Legislature, would end the use of STAR tests in math and English for the school year already under way – a year earlier than planned, and introduce the Measurement of Academic Performance and Progress (MAPP) tests, a new test aligned to the National Governors Association and College Board's ...
A noise dosimeter (American) or noise dosemeter (British) is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the Occupational Safety and Health (OSHA) 29 CFR 1910.95 Occupational Noise Exposure Standard ...
Standard Celeration Chart: To measure fluency, precision teaching utilizes a semi-logarithmic chart called a Standard Celeration Chart. This chart allows for demonstration of changes in rate of acquisition and allows the teacher to quickly assess a student’s performance accelerating through time. [1]

When diagnosing children, best practice suggests that a multi-test battery, i.e., multi-factored evaluation, should be used as learning problems, attention, and emotional difficulties can have similar symptoms, co-occur, or reciprocally influence each other. For example, children with learning difficulties can become emotionally distraught and ...
Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...
