The subversive songs of Tom Lehrer, the sardonic piano-wielding fugitive from Harvard, have corrupted generations of american citizens because he first begun recording and appearing within the Nineteen Fifties. His uniquely wicked wit has been compelled back on an unsuspecting public' through Tomfoolery, the degree revue according to his ever-trenchant commentary of the yankee scene.

Hearing loss 1 See page 6. Chapter |2 25 Psychoacoustics with age primarily affects high-frequency sensitivity, and there are statistically significant differences between men and women, with women faring better with age. It is not known whether this is an innate biological difference or is caused by more men than women working in noisier industrial environments and having noisier hobbies. S. Army does not allow recruits to be exposed to sound pressure levels over 140 dB, even briefly. Gunfire close at hand is the most likely source of sound that may cause a permanent loss with as little as one exposure.
The background grid represents the objective world, and the curves represent the response of an average human listener to that world in loudness. The contours are labeled in phons, one unit of subjective loudness, which is equal to the sound pressure level at 1 kHz. Taking the point 80 dB at 1 kHz as a reference, and following the 80 phon contour down to 20 Hz, shows that about 110-dB sound pressure level is needed to sound equally as loud as an 80-dB SPL 1-kHz tone. Human response to sound pressure level does not stop abruptly at high frequencies as shown, but this is the limit of experimental data.
In between the region where the level falls off as an inverse square with distance and the region where the level is constant with distance, there is an elbow in the curve of level versus distance. The midpoint of this elbow is the place where the direct sound field and the reverberant sound field levels are equal, called the critical distance from the source. All other things being equal, the critical distance varies in the following ways: l l As a room becomes more reverberant, for example by removing absorption, the critical distance gets shorter (because there will be more reverberation).
