A novel design of an actuator coupled with a low-hardness silicone elastomer called “the gel surround” is presented. It means that the output power of a conventional moving coil-type actuator can be greatly enhanced by applying the novel mechanism of...

A Novel Design for a Gel-Type DML Transducer Incorporating a Solid Panel Projecting Multiple Independent Sound Sources. (2010)
Presentation / Conference Contribution
Cho, M., Prokofieva, E., Barker, M., & Munoz, J. (2010). A Novel Design for a Gel-Type DML Transducer Incorporating a Solid Panel Projecting Multiple Independent Sound Sources.

The gel-type DML transducer (referred to as the gel transducer in this paper) excites a panel to radiate sound waves through the gel surround. The panel breaks into different characteristic modes of vibration as frequency increases. At high frequenci...

Improvement of Sound Quality by Means of Ultra-Soft Elastomer for the Gel Type Inertia Driven DML Type Transducer. (2010)
Presentation / Conference Contribution
Cho, M., Prokofieva, E., Munoz, J., & Barker, M. (2010). Improvement of Sound Quality by Means of Ultra-Soft Elastomer for the Gel Type Inertia Driven DML Type Transducer.

Unlike standard DML transducers, the gel-type inertia driven transducer (referred to as the gel transducer in this paper) designed as a mini woofer DML-type transducer, transfers its pistonic movement to a panel through the gel surround, thereby gene...

Methods of quality control of airborne and impact sound insualtion in newly built residential buildings. (2008)
Presentation / Conference Contribution
Prokofieva, E., & Smith, S. (2008). Methods of quality control of airborne and impact sound insualtion in newly built residential buildings.

The standard method of sound insulation testing in dwellings is pre-completion testing of separating walls and floors during the building process. The main disadvantage of this method is that if these structures fail to comply with building standar...
