The proposed surface area method compared the two different heating systems and successfully quantified the under- and over-heated sections of the treated rooms at any given time during the treatments.
Current 3D sound systems rely upon fixed loudspeaker arrangements and acoustically treated rooms that are not practical for home use.
Persons who entered aHPP treated rooms described an unpleasant smell and irritation of the eyes and upper airways.
Chlorpyrifos measurements were also made on samples collected from indicator toys placed within CPPAES treated rooms (H1 H3, H5 H9 samples collected in area A; H4 and H10 samples collected in area B).
Surface wipe samples were collected within treated rooms on days –1, 1, 2, 3, 5, 7, 9, and/or 11 from nontargeted surfaces (i.e., areas not directly sprayed with the pesticide).
After disinfection by xenon gas, a treated room remains at very low microbial levels indefinitely, meaning that there would be no need to repeat the decontamination procedure in a room, as long as no one has re-contaminated it.
The utterances were recorded in a sound treated room at the Department of Speech Sciences of the University of Helsinki using a high quality AKG 4000B condenser microphone and a high quality Digidesing Digi002 analogue to digital converter.
H2O2 concentration was measured at the end of vaporization/aerosolization in the corridor and rooms next to the treated room and in the treated room at the end of the entire process.
Pure-tone measurements were all conducted in a double-walled sound treated room meeting ISO 8253 1 standards of ambient sound pressure levels.
The participants listened to speech tokens individually in a double-walled, acoustically treated room where the ambient levels were within permissible limits [ 10].
