Early recordings were made entirely acoustically, the sound being collected by a horn and piped to a diaphragm, which vibrated the cutting stylus. Sensitivity and frequency range were poor, and frequency response was very irregular, giving acoustic recordings an instantly recognizable tonal quality. A singer practically had to put his or her face in the recording horn. Lower-pitched orchestral instruments such as cellos and double basses were often doubled (or replaced) by louder wind instruments, such as tubas. Standard violins in orchestral ensembles were commonly replaced by Stroh violins, which became popular with recording studios.
What instruments did not record well?
Lower-pitched orchestral instruments

This flexibility allows Catalan to use extraposition extensively, much more than French or Spanish. Thus, Catalan can have m'hi recomanaren ("they recommended me to him"), whereas in French one must say ils m'ont recommandé à lui, and Spanish me recomendaron a él. This allows the placement of almost any nominal term as a sentence topic, without having to use so often the passive voice (as in French or English), or identifying the direct object with a preposition (as in Spanish).
What languages use the passive voice more than Catalan?
French or English

By the mid-1970s, the agency had achieved a semi-automated air traffic control system using both radar and computer technology. This system required enhancement to keep pace with air traffic growth, however, especially after the Airline Deregulation Act of 1978 phased out the CAB's economic regulation of the airlines. A nationwide strike by the air traffic controllers union in 1981 forced temporary flight restrictions but failed to shut down the airspace system. During the following year, the agency unveiled a new plan for further automating its air traffic control facilities, but progress proved disappointing. In 1994, the FAA shifted to a more step-by-step approach that has provided controllers with advanced equipment.
