Military aircrew are exposed to high levels of noise during their working days/wee ks. Under the Control of Noise at Work Regulations :2005\, their employer has a duty of care for the aural health of their personnel. This study looked at the difference between noise levels measured b oth under the earcup of over-ear hearing protectio n and on the occluded side of in-ear comms devices in order to determine a transfer function for use in occupational noise risk assessments for milita ry aircrew\n \n 2. At present\, there is very litt le acoustic guidance relating to the effects that meteorological conditions can have on internal noi se levels. Current UK acoustic guidance favours dr y weather conditions with low wind speeds\; howeve r the UK only experiences these conditions for jus t under half the year\, meaning that some resident ial buildings are failing to provide suitable inte rnal noise levels during a large portion of the ye ar. This study discusses what effects meteorologic al conditions can have on high-rise buildings.\n \ n 3. An experiment was conducted in order to under stand how the vibrational response of fibre reinfo rced concrete is influenced by fibre type and volu me. The Coronavirus pandemic halted plans for phys ical impulse response testing\, so finite element analysis software was employed with an aim to simu late these experiments remotely. The simulation mo del was validated against real data and the experi ment found that the volume fraction of each studie d fibre type can be optimised to achieve desired m aterial and acoustic properties\n \n +++++++++++++ ++++++++++++++++++++++++++++++++++++++++\n \n This event is free to attend.\n \n If you are a Member  \;you can access the Zoom login details on th e members page\n \n https://www.ioa.org.uk/london- branch-0\n \n For Non-Members please email ioa@ioa .org.uk for details\n \n  \; CATEGORIES:Conference CALSCALE:GREGORIAN DTSTAMP;VALUE=DATE-TIME:20210120T170000 DTSTART;VALUE=DATE-TIME:20210120T170000 DTEND;VALUE=DATE-TIME:20210120T170000 URL:https://www.ioa.org.uk/civicrm/event/info?reset=1&id=604 END:VEVENT END:VCALENDAR
