Is 46db loud? The human ear can be sensitive to noise. The range of the dishwasher is between 46 to 60 decibels. This decibel level is loud enough to interrupt a normal conversation, but on the surface it may not sound like much. How loud is 34 decibels? In general, 34db is tolerab...
Normal breathing emits 10 dB, a soft whisper 30 dB, and a relaxing rain sound 50 dB. From 60 dB on, it is necessary to pay attention to prolonged exposure to noise. 85 dB is already equivalent to the noise of a congested street, 110 dB to a baby crying loudly beside you, and 120...

However, there is a reduction in slope of the hearing threshold below about 15 Hz from approximately 20 dB/octave above 15 Hz to about 12 dB/octave below. (Yeowart et al., 1967). The common assumption that “infrasound” is inaudible is incorrect, arising from an unfortunate choice of ...
Large headphones are essentially just two loudspeakers mounted on a strap that clamps firmly over your head. Earbuds work the same way but, as you would expect, everything inside them (the magnet, the coil of wire, and the diaphragm cone that makes sound) is shrunk down to a much smaller...
Sound (Image credit: What Hi-Fi?) It doesn’t take long to realise that theLS50have improved significantly. While the basic sonic character is instantly familiar, the new ones have gained a level of clarity and finesse the originals only hinted at. ...
However, it is clear from experiencing giggle sounds (personal experience), or, for the reader of this article by visual inspection of spectrograms (Figure 1 &2) as well as listening to the example sound clips (see Additional Files) that individual hyenas modulate both the fundamental frequency...
The WM-D6C is widely acknowledged to be one of the finest portable cassette machines ever made. It’s pocket-sized, if you have large pockets, and has sound quality and features that rival full-sized hi-fi cassette decks. It can also record, which is extremely unusual for a Walkman-form...
This is a cross post fromCheeseTalks.net, where I publish long form articles like this one. The original version has interactive charts and better navigation, but the text has been posted here in full for anybody who would prefer to read it on IndieDB. ...
Measured in decibels (dB), a logarithmic unit that expresses the ratio of a physical quantity to a reference level. Normal conversation is around 60 dB, whereas a jet engine might be over 140 dB. 3 Pitch The quality of a sound governed by the rate of vibrations producing it; the degree...
