There are 16,000 transfers of premature babies to medical facilities each year in the UK alone. The babies are often transported over large distances from rural to city locations over significant periods of time, in some cases two hours or more. The ambulances, helicopters or aircraft used are miniaturised intensive care units, containing all the equipment required to keep the baby alive.

But mechanical vibrations and noise from the equipment and transfer vehicle can provide significant, even life-threatening stress to the most vulnerable and delicate human lives. As we discovered when speaking to clinicians, transfers are sometimes aborted as a result of the stress that develops in the baby. These vehicles need materials and structures to reduce the noise and vibrations to tolerable levels. Continue reading
