Experimental Group

Physiological responses associated with the ratings of musical stimuli were investigated. For 101 university music and biology students in the experimental group, heart rate, blood pressure, and finger temperature were measured before and after listening to about 10 min. of music (Venus and Jupiter from Holst's The Planets) in an anechoic chamber. They also served as their own controls by sitting in silence for about 10 min. No significant differences were found on the three measures for the two musical stimuli between the musical or control conditions or between the two majors.

Passive Intermodulation

This paper presents an approximate method that allows the calculation of the maximum measurable gain (MMG) in an anechoic chamber. This method is realized by using a low passive intermodulation (PIM) medium-gain directional antenna. By reducing the distance between the antenna and the wall of the chamber to reduce path loss, the purpose of replacing a high-gain antenna with a medium-gain antenna is achieved. The specific relationship between distance and equivalent gain is given in this paper. The measurement interval is determined by the 3 dB beamwidth of the measurement antenna to scan the whole chamber. A set of corresponding data for the residual PIM level and the MMG of the chamber can be obtained by the method of measurement outlined herein. The feasibility of this method was verified by measurements in two PIM measurement chambers.
