ASTM E1130-16 使用铰接指数的开放式计划空间中语音隐私的客观测量的标准测试方法

1.1 This test method describes a means of objectively assessing speech privacy between locations in open plan spaces. This test method relies upon acoustical measurements, published information on speech levels, and standard methods for assessing speech communication. This test method does not measure the performance of individual open plan components which affect speech privacy; but rather, it assesses the privacy which results from a particular configuration of components (1, 2).2 1.2 This test method is intended to be a field test for the assessment of speech privacy in actual open plan spaces. However, this test method could be used in mock-up spaces and in environments arranged to simulate an open plan space. 1.3 This test method is suitable for use in many open plan spaces including traditional open offices, focus areas, and collaboration spaces. In addition to office buildings, these types of spaces will also be found in healthcare buildings, institutional spaces, schools, etc. It is not directly applicable for measuring the speech privacy between open plan and enclosed spaces or between fully enclosed spaces. 1.4 This test method relies upon the Articulation Index, which objectively predicts the intelligibility of speech. While both the Articulation Index and this test method can be expected to reliably predict speech privacy, neither predicts the specific effective speech privacy afforded to particular individual occupants. 1.5 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Diese Internationale Norm legt Anforderungen an die akustischen Eigenschaften von Vergleichsschallquellen fest: zeitliche Stabilität der abgestrahlten Schallleistung, Spektralverteilung, Richtcharakteristik. Die zeitliche Stabilität ist als Wiederholstandardabweichung definiert. Die Spektralverteilung kann entweder in einem reflexionsarmen Halbraum oder in einem Hallraum auf der Grundlage von Messungen der Schallleistungspegel in Frequenzbändern nach dieser Internationalen Norm verifiziert werden. Die Anforderungen an das Richtwirkungsmaß können nur in einem reflexionsarmen Halbraum verifiziert werden. In dieser Internationalen Norm sind außerdem Verfahren zur Bereitstellung von Daten zur Pegelkalibrierung und zur Bestimmung der Unsicherheit einer Schallquelle festgelegt, die hinsichtlich ihres Schallleistungspegels unter den in Abschnitt 4 definierten meteorologischen Bezugsbedingungen in Oktav- und Terzbändern und mit der Frequenzbewertung A für den Einsatz als Vergleichsschallquelle vorgesehen ist. Die vorliegende Internationale Norm wird als Kalibriernorm bezeichnet, obwohl das Verfahren in einem Prüflaboratorium (Prüfstand) durchgeführt wird und die Ergebnisse der Pegelkalibrierung nicht direkt im strengen messtechnischen Sinne auf nationale Messnormale rückführbar sind. Von den Prüflaboratorien, die dieses Verfahren durchführen, wird nicht erwartet, dass sie alle Anforderungen erfüllen, die üblicherweise an ein Kalibrierlaboratorium gestellt werden. ANMERKUNG ISO/IEC 17025 [15] legt verschiedene Anforderungen an die Kompetenz von Prüflaboratorien und Kalibrierlaboratorien fest. Laboratorien, in denen Vergleichsschallquellen nach dieser Internationalen Norm geprüft werden, erfüllen typischerweise die Anforderungen an Prüflaboratorien, nicht jedoch notwendigerweise diejenigen an Kalibrierlaboratorien. Diese Internationale Norm legt Verfahren für die Kalibrierung von Vergleichsschallquellen nicht nur im freien Feld über einer reflektierenden Ebene, sondern auch in Hallräumen bei verschiedenen Abständen zu den Begrenzungsflächen fest. Für die Position der Vergleichsschallquelle auf einer reflektierenden Ebene können die beiden vorstehend genannten Prüfumgebungen für Frequenzbänder ab mindestens 200 Hz als gleichwertig angesehen werden. Bei 160 Hz und darunter können gewisse systematische Unterschiede auftreten. Für Frequenzen unterhalb von 100 Hz ist ein alternatives Kalibrierverfahren unter Anwendung der Schallintensität angegeben.

GSO ISO 3740:2015 声学 噪声源声功率级的测定 基本标准使用指南

This International Standard gives guidance for the use of a series of nine International Standards describing various methods for determining the sound power levels from all types of machinery and equipment. It provides: — brief summaries of these basic International Standards; — guidance on the selection of one or more of these standards which are appropriate to any particular type (see clause 5 and annex D). The guidance given applies only to airborne sound. It is for use in the preparation of noise test codes (see ISO 12001) and also in noise testing where no specific noise test code exists. This International Standard is not intended to replace any of the details of, or add any additional requirements to, the individual test methods in the other basic standards referred to. These basic standards specify the acoustical requirements for measurements appropriate for different test environments and accuracies. It is important that specific test codes for various types of machinery and equipment be established and used in accordance with the requirements of these basic International Standards. Such standardized noise test codes will recommend the basic International Standard(s) to be used and will give detailed requirements on mounting and operating conditions for a particular family to which the machine under test belongs. If no specific noise test code exists for a particular type of machinery, this International Standard is of use for the choice of the most suitable of the basic standards. In all cases, the mounting and operating conditions of the machine under test should be in accordance with the general principles given in the basic standards. NOTE Two quantities which complement each other can be used to describe the sound emission of machinery or equipment. One is the emission sound pressure level at a specified position and the other is the sound power level. The International Standards which describe the basic methods for determining emission sound pressure levels at the work station and at other specified positions are the series ISO 11200 to ISO 11204.

GSO ISO 7196:2015 声学 次声测量的频率加权特性

This International Standard specifies a frequency-weighting characteristic, designated G, for the determination of weighted sound pressure levels of sound or noise whose spectrum lies partly or wholly within the frequency band from 1 Hz to 20 Hz. NOTES 1 In the case of wide-band noises whose spectrum embraces both the infrasonic and audio-frequency ranges, use of this International Standard to determine the infrasonic weighted sound pressure level is supplementary to the description of the same noise by methods already standardized which cover the audio-frequency range only, for example the description in terms of Α-weighted sound pressure level. The numerical value of the results will, in general, differ from the G-weighted result. No significance should be attached to this difference since the respective results relate to different parts of the noise spectrum with little overlap. 2 The G-weighting can also be used in connection with the determination of sound power levels and sound intensity levels. When measured with the G-curve, these are symbolized respectively as LWG and LIG.

GSO ISO 6926:2015 声学 用于确定声功率级的参考音频源的性能和校准要求

This International Standard specifies the acoustical performance requirements for reference sound sources: — temporal steadiness and repeatability of the sound power output, — spectral characteristics, — directivity index. The stability of the sound power output and the directivity index, for those sources where directivity is needed, are normally only determined in connection with pattern evaluation of the reference sound source. Because of the directivity measurements (for an exception see 5.5), pattern evaluations can only be performed in a hemi-anechoic environment. For regular verification measurements, only the frequency band sound power levels are normally determined. In this case measurements may be made in either hemi-anechoic or reverberant conditions. This International Standard also specifies procedures for calibrating a sound source intended for use as a reference sound source in terms of its sound power level under the reference condition that the characteristic impedance of air (ρc) is equal to 400 Ns/m3 in octave and in one-third-octave bands, and with frequency weighting A. Different procedures are specified for pattern evaluation and verification. NOTE Reference sound sources may also be used for measurements in one-half-octave bands, e.g. for ISO 9295. However, under these circumstances the stability and reproducibility limits stated in this International Standard will not apply. This International Standard specifies methods to calibrate reference sound sources not only in a free field over a reflecting plane but also in reverberation rooms at different distances from the boundary surfaces. For the position of the reference sound source on one reflecting plane, the two different test environments mentioned above are considered equivalent for frequency bands above or equal to 100 Hz. Below 100 Hz the measurement uncertainties are significantly different (see Table 1). This International Standard is applicable to a sound source which is intended for use as a reference sound source. The sound source may either be placed directly on the floor or mounted on a stand to be used at a certain elevation above the floor. For floor-mounted sources, this International Standard is valid only for sources whose maximum vertical dimension is less than 0,5 m and whose maximum horizontal dimension is less than 0,8 m. According to this International Standard only floor-mounted reference sound sources may be used when carrying out measurements on a measurement surface. For reference sound sources to be used or calibrated under reverberant conditions, no such restrictions on maximum dimensions apply.

GSO ISO 10846-1:2015 声学和振动 塑料元件声振动传输特性的实验室测量 第1部分：原理和指南

This part of ISO 10846 explains the principles underlying ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5 for determining the transfer properties of resilient elements from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. It is applicable to resilient elements that are used to reduce a) the transmission of audio frequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structure which may, for example, radiate fluid-borne sound (airborne, waterborne, or other), and b) the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act upon human subjects or cause damage to structures of any size when the vibration is too severe. The data obtained with the measurement methods, which are outlined in this part of ISO 10846 and further detailed in ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5, can be used for — product information provided by manufacturers and suppliers, — information during product development, — quality control, and — calculation of the transfer of vibrations through resilient elements. The conditions for the validity of the measurement methods are a) linearity of the vibrational behaviour of the resilient elements (this includes elastic elements with non-linear static load-deflection characteristics, as long as the elements show approximate linearity for vibrational behaviour for a given static preload), and b) the contact interfaces of the vibration isolator with the adjacent source and receiver structures can be considered as point contacts.

GSO ISO 532:2015 声学 如何计算声音的响度级别

This section of this International Standard specifies a method for calculating the loudness experienced by a typical (median) listener under the following conditions : 2.1 Diffuse sound field The sound is assumed to reach the listener's ears from all directions at the same intensity. This condition is approximated in an ordinary room. 2.2 Kind of spectrum The method is designed specifically for the types of broad band spectra most commonly encountered. Errors may arise if it is applied to certain types of line spectra, or to spectra having two or more sharp maxima that are separated by more than an octave. The magnitude of the error that may result from an unusual spectrum can only be determined experimentally. 2.3 Steady state The method is designed for noises that are steady rather than intermittent. Nevertheless, in a diffuse field, many noises of impulsive origin behave effectively as steady noises, because reverberation serves to diminish temporal discontinuities. NOTES 1 The error that may result with intermittent noises is not necessarily attributable to the calculation procedure. It may also be affected by the averaging characteristics of the meter used to determine the sound pressure levels. 2 Since the loudness of a sound depends upon the nature of the enclosure in which it is heard, it is important that comparative evaluations of different noise sources should be based on measurements made in essentially similar enclosures. 3 The band levels in the diffuse field should be measured by means of an omni-directional microphone located in the unobstructed sound field at the position of the listener's head.
