Zijlstra and colleagues probed the effects of seeing images of moving nature on patient anxiety levels. The team “investigated whether the use of motion nature projection in computed tomography (CT) imaging rooms is effective in mitigating psycho-physiological anxiety (vs. no intervention). . . . motion nature projection had a negative indirect effect on perceived anxiety through a higher level of perceived pleasantness of the room [when motion was present, anxiety was lower and the room was perceived to be more pleasant]. . . .
Research conducted by Largo-Wight, O’Hara, and Chen confirms earlier research that found that listening to nature sounds, is relaxing. The trio share that they had participants in their study listen to silence, or nature sounds (ocean waves), or classical music (Mozart) “for 15 min in an office or waiting room-like environment. . . .

Any of these conditions and problems can lead to dangerous, if not tragic outcomes.” Odeh and Guy completed “a review of the existing literature on plant-people interactions. . . . .
The National Research Council of Canada, Construction Division, has released a new edition of their Guide to Calculating Airborne Sound Transmission in Buildings. A copy is available free at the web address noted below. The introduction to the Guide reports that “The International Standards Organization (ISO) has published a calculation method, ISO 15712-1 that uses laboratory test data for sub-assemblies such as walls and floors as inputs for a detailed procedure to calculate the expected sound transmission between adjacent rooms. . . .
