An organization called the Penguin Club of Australia was founded in Sydney in 1937 and aimed at developing women's communication skills. [51] Led by Jean Ellis, the organization spread to other territories of Australia and current-day Papua New Guinea over time. [52] A main premise of the organization was that it was created "for women by women."
A speaker driver mounted on a finite baffle will display a physical phenomenon known as interference, which can result in perceivable frequency-dependent sound attenuation. This phenomenon is particularly noticeable at low frequencies where the wavelengths are large enough that interference will affect the entire listening area.
The "main" system (also known as Front of House, commonly abbreviated FOH), which provides the amplified sound for the audience, typically uses a number of powerful amplifiers that drive a range of large, heavy-duty loudspeakers—including low-frequency speaker cabinets called subwoofers, full-range speaker cabinets, and high-range horns. A ...
The term loudspeaker may refer to individual transducers (also known as drivers) or to complete speaker systems consisting of an enclosure and one or more drivers.. To adequately and accurately reproduce a wide range of frequencies with even coverage, most loudspeaker systems employ more than one driver, particularly for higher sound pressure level (SPL) or maximum accuracy.
Speech production is an unconscious multi-step process by which thoughts are generated into spoken utterances. Production involves the unconscious mind selecting appropriate words and the appropriate form of those words from the lexicon and morphology, and the organization of those words through the syntax.
Using a transition frame (which aligns the rigging on dissimilar systems), system engineers may sometimes hang a mid-format box below a large-format box to cover the closest audience members. Speaker boxes from different manufacturers are not mixed because each system has a particular 'voicing' which may be common to a single manufacturer.
Toastmaster is a general term, prevalent in the United States in the mid-20th century, referring to a person in charge of the proceedings of a public speaking event. The toastmaster is typically charged with organization of the event, arranging the order of speakers, introducing one or more of the speakers, and keeping the event on schedule. [1]
An active full-range loudspeaker. Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers.Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at ...
