In this study the TVIG has been found by numerical modeling as well as direct measurements using a Zwislocki coupler and the ear of a human subject, to be as much as 50dB greater than sound pressures typically generated while listening to sounds in an open environment.
Other devices such as ear buds and professional in-ear monitors, offer wider frequency response and thus expose listeners to potentially dangerous sound pressures.

This hose features high strength spiral steel wire reinforcement which provides a very flexible connection capability of withstanding high pumping pressures at API Grade D working pressures.

The blower door fan is turned on and the pressure inside the building is reduced, a number of readings are taken over a series of different pressures and these are processed through a computer software programme to crunch the numbers and produce the test result.
In the ideal problem the maximum pressure is proportional to R−3 , and comparison with the measured pressures near high explosives, in the range of radii where the two might be expected to be comparable, shows that these conclusions are borne out by experiment.
Neither the dishwasher nor the clothes washer require extremely high pressures.
