    The reproduction of sounds from all directions in the horizontal plane, commonly known as surround sound, offers new scope for greater realism of the reproduced sound and a new dimension for creative and dramatic effects. Although a large number of loudspeakers are almost certainly needed to reproduce surround sound convincingly, a worthwhile improvement may be given with just four loudspeakers in...

    Coherent light propagating within an optical fibre may be modulated by using a piezoelectric transducer to stress the fibre mechanically. This paper discusses the design and evaluation of this type of optical modulator and compares a number of modulator designs. The paper demonstrates the relative roles of the mechanical properties of the fibre and the component parts of the transducer in determin... View full abstract»

    After reviewing the ways in which impulsive noise is generated and methods by which it may be characterized, parameters suitable for an assessment of system performance are selected. Design considerations are given for equipment suitable for the measurement of these parameters and the effect of limitations in the equipment on the measured parameters is described. Methods of overcoming these limita... View full abstract»
