Sikhuphe International Airport in Swaziland has installed Acoustiblok, a sound abatement material to reduce the level of sound produced inside the new terminal.
Sikhuphe Airport will add a 3mm layer of the UL-approved Acoustiblok, which will increase a standard stud wall's soundproofing factor by 98%.
The heavy, limp Acoustiblok material will vibrate from the sound, and transform the acoustical energy into inaudible friction energy in a process referred to as isothermal adiabatic.
The construction of the $150m airport is set to be complete by early 2011.
The terminal's noise abatement measures are in line with those recommended by the World Health Organization.
