Walsh driver Loudspeakers. A novel omnidirectional loudspeaker invented by Lincoln Walsh and granted U.S. Patent 3,424,873 in 1969 (filled in 1964). Called a coherent-sound loudspeaker, a Walsh driver is an inverted-cone that radiates sound all around "... by means of a conical diaphragm operating as a wave transmission line." It is claimed to "... obtain full frequency range, high quality sound omnidirectionally from a single radiator." [US Patent 3,424,873]. Walsh's invention led to the founding of Ohm Acoustics, the exclusive manufacturer of loudspeakers based on Walsh drivers, and whose President/Chief Engineer, John Strohbeen further developed Walsh's concepts (U.S. Patent 4,483,015, et. al.) into what they are today. Also see refinements done by Peter Dick (DDD - Dick's dipole driver).

weighted average An average that takes into account the proportional relevance of each component, rather than treating each component equally. [IEEE Std 1680]

weighting filters Special filters used in measuring loudness levels, and consequently carried over into audio noise measurements of equipment. The filter design "weights" or gives more attention to certain frequency bands than others. The goal is to obtain measurements that correlate well with the subjective perception of noise. (Technically termed psophometric [pronounced "so-fo-metric"] filters, after the psophometer, a device used to measure noise in telephone circuits, broadcast, and other audio communication equipment. A psophometer was a voltmeter with a set of weighting filters.) Weighting filters are a special type of band-limiting filters designed to compliment the way we hear. Since the ear's loudness vs. frequency response is not flat, it is argued, we should not try to correlate flat frequency vs. loudness measurements with what we hear. Fair enough. Five weighting filter designs dominate (See: References: Metzler):

  • A-weighting (not official but commonly written as dBA) The A-curve is a wide bandpass filter centered at 2.5 kHz, with ~20 dB attenuation at 100 Hz, and ~10 dB attenuation at 20 kHz, therefore it tends to heavily roll-off the low end, with a more modest effect on high frequencies. It is the inverse of the 30-phon (or 30 dB-SPL) equal-loudness curve of Fletcher-Munson.
  • Editorial Note: Low-cost audio equipment often list an A-weighted noise spec -- not because it correlates well with our hearing -- but because it helps "hide" nasty low-frequency hum components that make for bad noise specs. Sometimes A-weighting can "improve" a noise spec by 10 dB. Words to the wise: always wonder what a manufacturer is hiding when they use A-weighting. "However, an exception has arisen: Digital products using A/D and D/A converters regularly spec S/N and dynamic range using A-weighting. This follows the semiconductor industry's practice of spec'ing delta-sigma data converters A-weighted. They do this because they use clever noise shaping tricks to create 24-bit converters with acceptable noise behavior. All these tricks squeeze the noise out of the audio bandwidth and push it up into the higher inaudible frequencies. The noise may be inaudible, but it is still measurable and can give misleading results unless limited. When used this way, the A-weighting filter rolls off the high frequency noise better than the flat 22 kHz filter and compares better with the listening experience. The fact that the low-end also rolls off is irrelevant in this application." From RaneNote 145, Audio Specifications

  • C-weighting (not official but commonly written as dBC) The C-curve is "flat," but with limited bandwidth, with -3 dB corners of 31.5 Hz and 8 kHz, respectively.
  • ITU-R 468-weighting (was CCIR, but since the CCIR became the ITU-R, the correct terminology today is ITU-R) This filter was designed to maximize its response to the types of impulsive noise often coupled into audio cables as they pass through telephone switching facilities. Additionally it turned out to correlate particularly well with noise perception, since modern research has shown that frequencies between 1 kHz and 9 kHz are more "annoying" than indicated by A-weighting curve testing. The ITU-R 468-curve peaks at 6.3 kHz, where it has 12 dB of gain (relative to 1 kHz). From here, it gently rolls off low frequencies at a 6 dB/octave rate, but it quickly attenuates high frequencies at ~30 dB/octave (it is down -22.5 dB at 20 kHz, relative to +12 dB at 6.3 kHz).
  • K-weighting Used for loudness normalization in broadcast, it "... is composed of two stages of filtering; a first stage shelving filter and a second stage high-pass filter." [from ITU-R BS.1770-2, page 3.
  • RLB-weighting (revised low-frequency B curve) Used for loudness normalization in broadcast, it is a second-order high pass with a -3 dB corner fixed at 60 Hz. See ITU-R BS.1770-1 , page 4.
  • TU-R (CCIR) ARM-weighting or ITU-R (CCIR) 2 kHz-weighting This curves derives from the ITU-R 468-curve above. Dolby Laboratories proposed using an average-response meter with the ITU-R 468-curve instead of the costly true quasi-peak meters used by the Europeans in specifying their equipment. They further proposed shifting the 0-dB reference point from 1 kHz to 2 kHz (in essence, sliding the curve down 6 dB). This became known as the ITU-R ARM (average response meter), as well as the ITU-R 2 kHz-weighting curve. (See: R. Dolby, D. Robinson, and K. Gundry, "A Practical Noise Measurement Method," J. Audio Eng. Soc., Vol. 27, No. 3, 1979) [Before using these terms be aware that the ITU-R, even after 20 years, takes strong exception to having its name used by a private company to promote its own methodologies.]
  • Z-weighting A new term defined in IEC 61672-1, the latest international standard for sound pressure level measurements. It stand for zero-weighting, or no weighting; i.e., a flat measurement with equal emphasis of all frequencies.

Wheatstone bridge An instrument used for measuring resistance. The circuit used is a 4-arm bridge, all arms of which are predominantly resistive. The bridge is a two-port network (i.e., it has two terminal pairs across opposite corners) capable of being operated in such a manner that when voltage is applied to one port, by suitable adjustment of the resistive elements in the network, zero output can be obtained at the signal output port (usually a meter). Under these circumstances the bridges is termed balanced. [Although the circuit used in a Wheatstone bridge was first described by Samuel Hunter Christie (1784-1865) -- the son of James Christie, founder of the well-known auction house -- in his paper "Experimental Determination of the Laws of Magneto-electric Induction" (1833), Sir Charles Wheatstone (1802-1875) received credit for its invention because of his adaptation of the circuit in 1843 for the measurement of resistance. Wheatstone also invented the concertina, the stereoscope and contributed significantly to the development of the telegraph.]

white noise 1. Physics. Analogous to white light containing equal amounts of all visible frequencies, white noise contains equal amounts of all audible frequencies (technically the bandwidth of noise is infinite, but for audio purposes it is limited to just the audio frequencies). From an energy standpoint white noise has constant power per hertz (also referred to as unit bandwidth), i.e., at every frequency there is the same amount of power (while pink noise, for instance, has constant power per octave band of frequency). A plot of white noise power vs. frequency is flat if the measuring device uses the same width filter for all measurements. This is known as a fixed bandwidth filter. For instance, a fixed bandwidth of 5 Hz is common, i.e., the test equipment measures the amplitude at each frequency using a filter that is 5 Hz wide. It is 5 Hz wide when measuring 50 Hz or 2 kHz or 9.4 kHz, etc. A plot of white noise power vs. frequency change is not flat if the measuring device uses a variable width filter. This is known as a fixed percentage bandwidth filter. A common example of which is 1/3-octave wide, which equals a bandwidth of 23%. This means that for every frequency measured the bandwidth of the measuring filter changes to 23% of that new center frequency. For example the measuring bandwidth at 100 Hz is 23 Hz wide, then changes to 230 Hz wide when measuring 1 kHz, and so on. Therefore the plot of noise power vs. frequency is not flat, but shows a 3 dB rise in amplitude per octave of frequency change. Due to this rising frequency characteristic, white noise sounds very bright and lacking in low frequencies. [Here's the technical details: noise power is actually its power density spectrum - a measure of how the noise power contributed by individual frequency components is distributed over the frequency spectrum. It should be measured in watts/Hz; however it isn't. The accepted practice in noise theory is to use amplitude-squared as the unit of power (purists justify this by assuming a one-ohm resistor load). For electrical signals this gives units of volts-squared/Hz, or more commonly expressed as volts/root-Hertz. Note that the denominator gets bigger by the square root of the increase in frequency. Therefore, for an octave increase (doubling) of frequency, the denominator increases by the square root of two, which equals 1.414, or 3 dB. In order for the energy to remain constant (as it must if it is to remain white noise) there has to be an offsetting increase in amplitude (the numerator term) of 3 dB to exactly cancel the 3 dB increase in the denominator term. Thus the upward 3 dB/octave sloping characteristic of white noise amplitude when measured in constant percentage increments like 1/3-octave.] See noise color. 2. Music.

widget (perhaps alteration of gadget) 1. A small mechanical device or control; a gadget. 2. An unnamed or hypothetical manufactured article. [AHD] 3. As developed by Guinness, a small disk with a pinprick-size hole that fits inside their beer cans. As the beer is packaged, a small amount of stout is forced into the widget and held there under pressure. Once the pressure is released by opening the can, the beer is freed from the widget and a stream of bubbles flows upward. Now when the stout is poured, it looks like a pub-poured draught with the characteristic Guinness head (thick collar of foam), without the widget it looks like any other beer. It also reproduces the creamy texture and low carbonation of a draught pint. Now also used by Murphy's and Beamish.

wiring classes U.S. National Electrical Code (NEC) defines three classes of wiring according to their fire and shock hazard potential:

  • Class 1 Where both fire and shock hazards exist, i.e., the wiring can deliver enough current for a fire hazard and enough voltage for a shock hazard. The most common example is AC power running to equipment. This class requires prevention of all touching and barriers against fire.
  • Class 2 Where neither fire or shock hazard exists, i.e. the wiring cannot deliver enough current (internal limiting) for a fire hazard and not enough voltage for a shock hazard. Examples here are all normal audio interconnect plus most power amplifier output wiring.

  • Class 3 Where there is not a fire hazard but there is a shock hazard, i.e., the wiring cannot deliver enough current (internal limiting) for a fire hazard, but can deliver enough voltage for a shock hazard. Requires touch-proof terminals; seen in audio for very high-output power amplifiers.
