PSB Speakers is a Canadian loudspeaker company founded in 1972 by Paul Barton. The company is named after Barton and his wife Sue. The company is headquartered in Pickering, Ontario, and is now part of the Lenbrook Group. PSB Speakers produces many lines of speakers from the high-end Platinum series to the entry-level Alpha series. Their speakers are respected by audiophiles who prefer a flat frequency response curve. Paul Barton has spent a lot of time during the past few decades researching his speakers in the anechoic chambers at the National Research Council in Ottawa Ottawa (, ; Canadian French: ) is the capital city of Canada. It is located at the confluence of the Ottawa River and the Rideau River in the southern portion of the province of Ontario. Ottawa borders Gatineau, Quebec, and forms the core ....

Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...

Pickering, Ontario
Pickering (2021 population 99,186) is a city located in Southern Ontario, Canada, immediately east of Toronto in Durham Region. Beginning in the 1770s, the area was settled by primarily ethnic British colonists. An increase in population occurred after the American Revolutionary War, when the Crown resettled Loyalists and encouraged new immigration. Many of the smaller rural communities have been preserved and function as provincially significant historic sites and museums. The city also includes the development of Durham Live, a multi-billion-dollar casino complex. History Early period The present-day Pickering was Aboriginal territory for thousands of years. The Wyandot (called the Huron by Europeans), who spoke an Iroquoian language, were the historical people living here in the 15th century. Archeological remains of a large village have been found here, known as the Draper Site. Later, the Wyandot moved northwest to Georgian Bay, where they established their historic homela ...

Frequency Response
In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and phase of the output as a function of input frequency. The frequency response is widely used in the design and analysis of systems, such as audio and control systems, where they simplify mathematical analysis by converting governing differential equations into algebraic equations. In an audio system, it may be used to minimize audible distortion by designing components (such as microphones, amplifiers and loudspeakers) so that the overall response is as flat (uniform) as possible across the system's bandwidth. In control systems, such as a vehicle's cruise control, it may be used to assess system stability, often through the use of Bode plots. Systems with a specific frequency response can be designed using analog and digital filters. The frequency response characterizes systems in the frequency domain, just as the impulse response characterizes systems in the ...

Anechoic Chamber
An anechoic chamber (''an-echoic'' meaning "non-reflective") is a room designed to stop reflections of either sound or electromagnetic waves. They are also often isolated from energy entering from their surroundings. This combination means that a person or detector exclusively hears direct sounds (no reflected sounds), in effect simulating being outside in a free field. Anechoic chambers, a term coined by American acoustics expert Leo Beranek, were initially exclusively used to refer to acoustic anechoic chambers. Recently, the term has been extended to other RF and Sonar anechoic chambers, which eliminate reflection and external noise caused by electromagnetic waves. Anechoic chambers range from small compartments the size of household microwave ovens to ones as large as aircraft hangars. The size of the chamber depends on the size of the objects and frequency ranges being tested. Acoustic anechoic chambers The requirement for what was subsequently called an anechoic ...

Electronics Companies Established In 1972
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small el ...
