| Title | Paper, 'Effect of floor-deafening on the sanitary condition of dwelling houses' by Etta Johnstone and Thomas Carnelley |
| Creator | Johnstone; Etta (fl 1889) |
| Carnelley; Thomas (1854-1890); British chemist |
| Date | 1889 |
| Description | The authors write: '“Deafening” is the material which is laid upon boards fitted in between the joists of a floor to prevent the passage of sound into the room below. This material is used largely on the Continent and in many parts of this country, especially in Scotland, and is supposed to consist of a mixture of coarse mortar and smith’s ashes, but in general it appears to be of a much more questionable nature, particularly in the case of low-class houses. It is also supposed by some builders to prevent the passage of smell; but houses are known to have been rendered uninhabitable by its presence, the cinders, which form the great bulk of the substance, being more or less contaminated according to the place whence obtained and other attendant circumstances.'
