The first World Championship Grand Prix was held in 1950 at Silverstone; since then 77 circuits in total have hosted a Grand Prix.A lot of classic (older) circuits have hosted Grands Prix using different configurations throughout their history: Nürburgring, Spa-Francorchamps, Monza, etc. Taking Nürburgring as an example, the first World Championship race there used the 22.835 km (14.189 mi ...
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
A component having a 'flat' frequency response will not change the weighting (i.e., intensity) of signal content across the specified frequency range. The frequency range often specified for audio components is between 20 Hz to 20 kHz, which broadly reflects the human hearing range (the highest audible frequency for most people is less than 20 ...
Most (driving) penalties in one race: 5: Esteban Ocon (2023 Austrian Grand Prix) [36] Most grid-place (engine) penalties for one race: 70: Jenson Button (2015 Mexican Grand Prix) [37] Youngest average age of podium finishers: 23 years, 256 days: 2019 Brazilian Grand Prix (Max Verstappen, Pierre Gasly, Carlos Sainz Jr.) [38] Oldest average age ...
The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m 2). One application is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity. [3] Sound intensity is not the same physical quantity as sound pressure. Human hearing is sensitive to sound pressure which is ...
An audio signal is a representation of sound, typically using either a changing level of electrical voltage for analog signals, or a series of binary numbers for digital signals. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz, which corresponds to the lower and upper limits of human hearing .
In high fidelity audio, an amplifier requires a flat frequency response of at least 20–20,000 Hz, with a tolerance as tight as ±0.1 dB in the mid-range frequencies around 1000 Hz; however, in telephony, a frequency response of 400–4,000 Hz, with a tolerance of ±1 dB is sufficient for intelligibility of speech.

It can be proven (with the help of a sum-to-product trigonometric identity) that the sum of two unit-amplitude sine waves can be expressed as a carrier wave of frequency f 1 + f 2 / 2 whose amplitude is modulated by an envelope wave of frequency f 1 - f 2 / 2 : [3]
