CreatorSwinton; Alan Archibald Campbell (1863-1930); British electrical engineer
Date15 April 1921
DescriptionInforms that at his suggestion, Fournier d'Albe will be asked to show the Optophone at the forthcoming Royal Society Soiree. Suggests that if he accepts the invitation, that he should show the instrument with some amount of amplificationm as in such occasions, there is always a good deal of general noise, which makes it very difficult to hear weak sounds, even with the telephone held close to the ear.
