Krohn (1891, see related literature) describes this instrument as follows:
"5. Schall-apparat. This apparatus is constructed for the purpose of determining the direction of sound. It consists of a very small box containing electrical apparatus, that makes the ticking noise, which acts as auditory stimulus. This is enclosed in a large oak box, deadened by a lineing of felt and zinc, and the space between the two boxes filled with water. The electrical apparatus can be set going from without by means of a small Grove cell battery. Through one side of the outer box are inserted 3 iron tubes that enter the inner box, and through which the sound can be transmitted. To these are attached rubber tubes about four feet long, at the end of which are bell-shaped guttapercha cups that fit over the ear; these can be held at any angle, and thus the sound made to come from any direction. The subject then makes his judgment as to the direction in each case. It is a very convenient and and cannot be out of order. Price 60 marks." |
