Subject: hypoxia / hypercapnia associated with extended duration in sound rooms? From: Erik Larsen <elarsen@xxxxxxxx> Date: Tue, 13 Sep 2016 19:47:16 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001a113f53bee23c70053c68e1b3 Content-Type: text/plain; charset=UTF-8 Hi everyone, is anyone familiar with studies that have looked at oxygen and carbon dioxide changes in sound booths / rooms, when occupied by a test subject during extended periods of time? Depending on whether sound rooms are ventilated or not, changes in the composition of the air relative to ambient may change more or less, also depending on the volume of the room, and how long the subject remains inside without opening the door. I'm interested to know whether anything is known regarding hypoxia or hypercapnia in test subjects associated with staying in sound rooms for extended periods of time. Patients with compromised health may be especially sensitive. If anyone has used or knows about "good experimental practice" in audiology / hearing research settings in terms of opening the sound room door and letting it ventilate passively for a few minutes, that would also be of interest. Thanks for any insights, Erik --001a113f53bee23c70053c68e1b3 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">Hi everyone,<div><br></div><div>is anyone familiar with st= udies that have looked at oxygen and carbon dioxide changes in sound booths= / rooms, when occupied by a test subject during extended periods of time?<= /div><div><br></div><div>Depending on whether sound rooms are ventilated or= not, changes in the composition of the air relative to ambient may change = more or less, also depending on the volume of the room, and how long the su= bject remains inside without opening the door.</div><div><br></div><div>I&#= 39;m interested to know whether anything is known regarding hypoxia or hype= rcapnia in test subjects associated with staying in sound rooms for extende= d periods of time.
