This includes transactions processed through the mobile banking facility as well as the smartphone app facility. Internet Banking means the service we offer by which you can access and transact on a nominated account by using a personal computer and accessing via our website. 1 of 1999) īouquet or “bouquet of channels” means an assortment of distinct channels offered together as a group or as a bundle by the Broadcaster and all its grammatical variations and cognate expressions shall be construed accordingly Public Finance Management Act ’ means the Public Finance Management Act, 1999 (Act No. ![]() POPIA means the Protection of Personal Information Act 4 of 2013 LHSIA means the Local Health System Integration Act, 2006, and the regulations made under it, as it and they may be amended from time to time Octave band background sound level measurements for residential areas near the proposed Indeck plant site show background noise levels in the lowest regulated frequencies (31.5-125 ) as low as 35-40 dB during both daytime and nighttime hours. This data has been reported by Enbridge and Union for four years. Octave band sound power levels were obtained by applying adjustments recommended by Crocker (1998). Octave band: a band of sound covering a range of frequencies such that the highest frequency is twice the lowest frequency, as defined in ANSI Standard S1.11.One-third octave band: a band of sound covering a range of frequencies such that the highest frequency is the cube root of two times the lowest frequency, as defined in ANSI Standard S1.11. The primary requirements for obtaining the outdoor equipment’s sound levels are:♦ Accurate calibrated sound measurement equipment should be used.♦ Octave band sound pressure levels are mandatory.♦ he sound level data should indicate the true directivity effects of the unit’s sound (there should be no nearby buildings or obstructions to distort the true radiation pattern of the unit test).♦ The measurement distance should be specified. Octave band analysis and identification of predominant frequencies of operation. Octave band analyzer calibrated in the Preferred Frequencies (American Standards Association Sl-6-1960, Preferred Frequencies for Acoustical Measurement) shall be used with Table A. Octave band sound pressure levels will be obtained for ambient room conditions with equipment not operating and also with the installed equipment operating per plans and specifications. Octave band analyzers calibrated in the preferred frequencies (American National Standards Institute Standard S 1.6-1967, Preferred Frequencies and Band Numbers for Acoustical Measurements) shall be used. * ) fd = 10^ 0.Octave band corrections may be employed in meeting the response specification. %% Calculate Third Octave Bands (base 10) in Matlab fcentre = 10.^ ( 0.1. A one-third octave band is defined as a frequency band whose upper band-edge frequency (f2) is the lower band frequency (f1) times the cube root of two. A band is said to be an octave in width when the upper band frequency is twice the lower band frequency. For this reason, a scale of octave bands and one-third octave bands has been developed. ![]() Each band covers a specific range of frequencies. The whole frequency range is divided into sets of frequencies called bands. Īnalyzing a source on a frequency by frequency basis is possible but time-consuming. 2/1 = 1200 cents ≈ 10 0.301.įractional octave bands such as + 1⁄ 3 or + 1⁄ 12 of an octave are widely used in engineering acoustics. In this context an octave can be a factor of 2 or a factor of 10 0.3.
