Article: 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.

Question: How did the NBC Othacoustic curve relate to the NAB curve?
Ans: remarkably similar

Article: At the 29 August Arab League summit in Khartoum, Nasser's usual commanding position had receded as the attending heads of state expected Saudi King Faisal to lead. A ceasefire in the Yemen War was declared and the summit concluded with the Khartoum Resolution. The Soviet Union soon resupplied the Egyptian military with about half of its former arsenals and broke diplomatic relations with Israel. Nasser cut relations with the US following the war, and, according to Aburish, his policy of "playing the superpowers against each other" ended. In November, Nasser accepted UN Resolution 242, which called for Israel's withdrawal from territories acquired in the war. His supporters claimed Nasser's move was meant to buy time to prepare for another confrontation with Israel, while his detractors believed his acceptance of the resolution signaled a waning interest in Palestinian independence.

Question: What agreement ended the Yemeni civil war?
Ans: Khartoum Resolution

Question: What affect does different pronunciations in the two areas of Catalan speakers produce?
Ans:
