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 was a benefit to broadcasters of recording standards?
programming sounded more lifelike.

In recent years, there has been a rise of indigenous movements in the Americas (mainly South America). These are rights-driven groups that organize themselves in order to achieve some sort of self-determination and the preservation of their culture for their peoples. Organizations like the Coordinator of Indigenous Organizations of the Amazon River Basin and the Indian Council of South America are examples of movements that are breaking the barrier of borders in order to obtain rights for Amazonian indigenous populations everywhere. Similar movements for indigenous rights can also be seen in Canada and the United States, with movements like the International Indian Treaty Council and the accession of native Indian group into the Unrepresented Nations and Peoples Organization.
What is an example of a movement which is working to obtain rights for Amazonian populations everywhere?
