Measurement errors from instruments are often modeled using the uniform distribution to determine the range of large public address system, acoustical engineers use a method of triangulation to measure the shock waves sent out by the speakers. The time at which the waves arrive at the sensors must be measured accurately. In this context, a negative error means the signal arrived too early. A positive error means the signal arrived too late. Measurement errors in reading these times have a uniform distribution from -0.05 to +0.05 microseconds. (Reference: J. Perruzi and E. Hilliard, “Modeling Time Delay Measurements Errors,”
