&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Approved document E: Resistance to the passage of sound, 2003 edition incorporating 2004, 2010, 2013 and 2015 amendments, defines a frequency band as: ‘A continuous range of frequencies between stated upper and lower limits.”&lt;br /&gt;
&lt;br /&gt;
It defines an octave band as: ‘A frequency band in which the upper limit of the band is twice the frequency of the lower limit.’&lt;br /&gt;
&lt;br /&gt;
And a one-third octave band as: ‘A frequency band in which the upper limit of the band is 21/3 times the frequency of the lower limit.&lt;br /&gt;
