To quickly assess the difficulty of the text, read a short excerpt:
Notice the way the sound appears. How do you suppose it reaches the internal ear? 3. Close the ears as before and take a pencil between your teeth. Press the end of the pencil on a watch and see whether you can hear the ticking. 4. Spread a piece of thick cloth on the bench and clamp a metre rule vertically beside it. Test your acuteness of hearing by sitting 5 feet away and getting someone to drop a pin on to the cloth from various gradually increasing heights until you just hear the faint thu...d that the pin makes on striking the cloth. 5. Hold a watch exactly one metre from the ear. Then suddenly move it 2 cm. Further away. Notice if the ticking seems fainter. Replace it and take it suddenly 4 cm. Further away. Repeat until a distance is reached which just makes the ticking fainter. In this way compare the power of distinguishing loudness of sounds possessed by various people. 6. Make for yourself from a sycamore twig a whistle of variable note. The bark is loosened by hammering it. The wood inside becomes the moving plunger.
