An Inexpensive Type of Sound-Proof Room Suitable for Zoological Research
1 Madingley Ornithological Field Station, Department of Zoology, University of Cambridge
The design of an inexpensive sound-proof room, virtually sound-proof to audio-frequencies of 2 kc. and above, is described. Since for the purposes of many zoological experiments low frequencies can safely be disregarded, it is felt that on account of cheapness and relative ease of construction, this type of sound-proof room has much to recommend it.
