Using Lecture Demonstrations to Visualize Biological Concepts

INTRODUCTION The use of visual aids in biology has traditionally focused on laboratory activities and demonstrations (3, 6, 8, 12, 15–18). However, a limited number of authors have suggested activities suitable for lectures. Such activities reinforce the concepts taught and require less equipment, time, and expense than laboratory activities Moreover, simple demonstrations are easy for students...

Lecture Halls - Room Acoustics and Sound Reinforcement

This paper describes our experience with lecture halls with regard to the room acoustics, sound reinforcement and audio frequency induction loops for persons with hearing impairment. The optimum reverberation time and geometrical conditions for classrooms are well known. Recent research basically confirms this knowledge but indicates the need for shorter reverberation times. However, many exist...

Architectural Acoustics: General Topics in Architectural Acoustics

The Audio Arts and Acoustics department at Columbia College in Chicago acquired a new building in 2003. The facility, a former bank, contained an old steel and concrete vault that was converted to a reverberation chamber. The acoustic properties of the space, including reverberation time, modal density, and early reflection maps were analyzed and compared to a computer model. Reflectograms were...
