| In addition, fluid flows, airflows, strain forces, and acoustical waves that were previously imperceptible might now be detected. |
| Research using sonograms, hydrophones, and other acoustical devices have shown that that these whales produce two sounds termed A or B calls. |
| Listening to the orchestra perform these profound works in the Ulster Hall demonstrated once again what fine acoustical properties the hall has. |
| These qualities have made asbestos popular to be used in insulation, acoustical tiles, floor tiles, and automotive brake assemblies. |
| In the courtrooms, fabric-wrapped acoustical panels give the walls an ashlar pattern similar to that of the exterior. |
| These provide thermal and acoustical insulation, strength with low weight, and coverage with few heat loss paths. |
