Acoustic radiometer
An acoustic radiometer is an instrument designed to measure the intensity of acoustic (sound) radiation. It typically quantifies sound pressure levels and can provide insights into the energy output of acoustic sources or the propagation of sound waves in various environments. Acoustic radiometers can be used in a range of applications, including: 1. **Environmental Monitoring**: Measuring noise pollution in urban areas or natural habitats. 2. **Scientific Research**: Studying sound propagation in different media, including water and air.
Active Bat
The Active Bat is a system used for tracking and studying bats, particularly their behavior and flight patterns. It often consists of a combination of ultrasonic transmitters attached to the bats and a network of receivers that capture the ultrasonic signals emitted by the bats. This technology provides researchers with valuable data regarding bat movements, foraging habits, roosting sites, and interactions with their environment.
Punch in/out
"Punch in" and "punch out" refer to the process of recording the start and end times of an employee's work shift, typically using a time clock or electronic timekeeping system. This method is often used in businesses to track employee attendance and working hours for payroll purposes. - **Punch In**: This is the action an employee takes to indicate the beginning of their workday.
Realistic (brand)
Realistic is a brand that was historically known for its line of consumer electronics, particularly in the areas of radios, cassette players, and other audio equipment. It was primarily associated with the Tandy Corporation, which owned RadioShack. The Realistic brand was prominent during the 1970s and 1980s, offering affordable audio gadgets and electronics to consumers. Products under the Realistic brand were often recognized for their value, providing a combination of decent quality and affordability.
Repeating waveforms
Repeating waveforms refer to waveforms that exhibit a periodic nature, meaning they repeat their shape at regular intervals over time. These waveforms can be described mathematically and are commonly found in various fields such as physics, engineering, and music. Key characteristics of repeating waveforms include: 1. **Period (T)**: The duration of one complete cycle of the waveform. It's the time taken for the waveform to repeat itself.
Lionel Cooper (mathematician)
Lionel Cooper is a noted mathematician recognized for his contributions in the field of mathematics. He is particularly known for his work in the areas of combinatorial game theory, discrete mathematics, and operations research. His research often involves investigating mathematical structures and their applications in various fields, such as computer science and economics. However, detailed information regarding his specific contributions and publications may not be widely documented or may vary based on the particular area of interest within mathematics.
Alexander Friedmann
Alexander Friedmann was a Russian physicist and mathematician known for his pioneering work in cosmology during the early 20th century. He is best known for the Friedmann equations, which are central to modern cosmology and describe how the universe expands over time. Friedmann's equations emerged from his analysis of Einstein's general theory of relativity and addressed the dynamics of a homogeneous and isotropic universe. His work laid the groundwork for the Big Bang theory of the universe's origin.
Legacy Audio
Legacy Audio is a company known for designing and manufacturing high-end audio equipment, specifically loudspeakers and related audio components. Established in 1985 and based in the United States, Legacy Audio focuses on delivering high-fidelity sound reproduction through innovative design and engineering. Their products often integrate advanced technologies, such as multi-driver systems, proprietary drivers, and sophisticated cabinet designs, to achieve optimal sound quality and performance in various listening environments.
Long-term Predicted Excitation Coding (LPEC) is a technique used in speech coding and other audio processing applications to efficiently represent and transmit voice signals. It is particularly relevant in contexts where bandwidth is limited, such as in telecommunications or streaming applications. ### Key Concepts of LPEC: 1. **Excitation Coding**: This refers to the method of representing the excitation signal that drives the vocal tract model in speech synthesis.
Loudness compensation
Loudness compensation is a feature used in audio processing and playback systems to adjust the equalization of sound based on the perceived loudness at different volume levels. Human hearing does not respond equally across all frequencies at low and high loudness levels; we tend to hear bass and treble frequencies less prominently when listening at lower volumes. To counteract this, loudness compensation boosts certain frequency ranges to ensure that the audio remains balanced and pleasant to listen to, even at lower sound levels.
MIL-CD
MIL-CD, or "Millennium CD," is a disc format that was introduced in the late 1990s primarily for use with the Sega Dreamcast gaming console. It is a variation of the standard CD-ROM format but includes enhancements that allow for additional data storage and multimedia capabilities. MIL-CD allows for the storage of a larger amount of data than a regular CD, which makes it suitable for interactive multimedia applications such as video games, music, and other multimedia content.
MP3 Surround
MP3 Surround is an extension of the MP3 audio format that adds support for multi-channel audio, allowing for a surround sound experience. While standard MP3 files typically contain stereo audio (two channels), MP3 Surround can support multiple channels, such as 5.1 surround sound setups, which include front left, front right, center, subwoofer, and rear channels.
Magic Mic
Magic Mic is a brand of karaoke microphones that allows users to sing along to music tracks, often featuring built-in speakers, sound effects, and multi-functionality. These microphones typically connect to smartphones, tablets, or other audio devices via Bluetooth or auxiliary inputs, enabling users to access a wide range of songs and karaoke settings. Some models come with additional features such as voice modulation, echo effects, and recording capabilities, making them popular for parties, gatherings, and personal use.
Magnetostatic loudspeaker
A magnetostatic loudspeaker, also known as a magnetostatic speaker, is a type of electroacoustic transducer that converts electrical signals into sound using magnetostatic principles. These speakers typically use a diaphragm that is sandwiched between two magnetic fields produced by permanent magnets. Unlike traditional dynamic speakers, which use an electromagnetic coil to induce sound, magnetostatic speakers operate on the principle of force exerted on the diaphragm by the magnetic field.
Nady Systems, Inc.
Nady Systems, Inc. is a company that specializes in audio products, particularly wireless microphone systems, and other audio equipment. Founded in 1973 by Nady Khokhar, the company has been a significant player in the pro audio industry, providing solutions for musicians, performers, and audio professionals.

N41 (nebula)
N41, also known as LBN 762 or the Drunken Dragon Nebula, is a dark nebula located in the constellation of Cassiopeia. Dark nebulae are regions of space that contain dust and other materials, blocking the light from stars and other objects behind them. N41 is notable for its distinctive shape, which some observers think resembles a dragon.
Headshell
A headshell is a component of a turntable or a tonearm that holds the phono cartridge and allows for the mounting of the cartridge to the tonearm. It is typically a small, removable piece that connects the tonearm to the cartridge, providing both mechanical support and electrical connectivity. Headshells often come in different designs, weights, and materials, which can affect the overall sound quality and performance of the turntable setup.
