The lateral cut NAB curve was remarkably similar to the NBC Orthacoustic curve that evolved from practices within the National Broadcasting Company since the mid-1930s. Empirically, and not by any formula, it was learned that the bass end of the audio spectrum below 100 Hz could be boosted somewhat to override system hum and turntable rumble noises. Likewise at the treble end beginning at 1,000 Hz, if audio frequencies were boosted by 16 dB at 10,000 Hz the delicate sibilant sounds of speech and high overtones of musical instruments could survive the noise level of cellulose acetate, lacquer/aluminum, and vinyl disc media. When the record was played back using a complementary inverse curve, signal-to-noise ratio was improved and the programming sounded more lifelike.
What bass settings were needed to eliminate hum?
below 100 Hz

On April 20, the People's Daily published a report entitled "Overseas Chinese rally against biased media coverage, for Olympics". It included images of Chinese people demonstrating in France, the United Kingdom, Germany and the United States. One picture showed Chinese demonstrators holding a sign which claimed, incorrectly, that the BBC had not reported on Jin Jing. The People's Daily quoted one protestor who claimed the "BBC on some of the recent events has misled the British public and the rest of the world by providing intensive untruthful reports and biased coverage."

The library system of the university is divided between the main library and each of the colleges and schools. The main building is the 14-story Theodore M. Hesburgh Library, completed in 1963, which is the third building to house the main collection of books. The front of the library is adorned with the Word of Life mural designed by artist Millard Sheets. This mural is popularly known as "Touchdown Jesus" because of its proximity to Notre Dame Stadium and Jesus' arms appearing to make the signal for a touchdown.
