1. Apparatus for providing a measure of the time taken for sound to travel a predetermined distance, comprising a transmitter electroacoustic transducer for transmitting an acoustic signal, and a receiver electroacoustic transducer, spaced apart from the transmitter electroacoustic transducer, for receiving the acoustic signal transmitted by the transmitter electroacoustic transducer, when the apparatus is in use, the apparatus having a sound reflective surface spaced apart from the receiver electroacoustic transducer so that the latter also receives a reflection of that signal, and timing electrical circuitry connected to the receiver electroacoustic transducer which circuitry serves to provide a measure of the time delay between the respective receptions by the receiver electroacoustic transducer of that signal and its reflection.
