+  <abstract>
+    <p>
+      Infra sound refers to sound waves below the range of human hearing.
+      Infra sound comes from a number of natural phenomena including weather
+      changes, thunder, and ocean waves. Common man made sources include
+      heating and ventilation systems, industrial machinery, moving vehicle
+      cabins (air, trains, cars), and energy generation (wind turbines, gas
+      plants).
+    </p>
+    <p>
+      In this talk Richard Mann will present equipment he has built to measure
+      infra sound, and analyse some of the infra sound he has recorded.
+    </p>
+    <p>
+      Note: In Winter 2016 Richard Mann will be offering a new course, in
+      Computer Sound. The course will appear as CS489/CS689 ("Topics in
+      Computer Science"). This is a project-based course (60% assignments, 40%
+      project, no final). Details at his web page,
