| In that way, we should obtain a sound energy policy, solidarity and a better Europe. |
| The length of time during which the sound energy ceases, and the electrical energy lasts depends not on the principle of the telephone, but on the length of the wire. |
| Phacoemulsification is the procedure in which the lens is dissolved using sound energy or ultrasound. |
| At increasing distances from the source, the sound energy is spread over an increasingly large area. |
| So our ear can overcome the great inefficiency of the sound-production mechanisms by being super sensitive to the trickle of sound energy that is produced. |
| When fireworks are lit, the chemical potential energy is converted into light, heat and sound energy. |
