Pump up the volume… ESA’s Large European Acoustic Facility (LEAF) will be on view to visitors at next month’s ESA Open Day in the Netherlands, along with other facilities in the establishment’s Test Centre. LEAF subjects satellites to the same noise a launcher produces as it lifts off, producing a range of noise up to more than 154 decibels, like standing close to multiple jets taking off.
