Up mixes (emulates) 1.0 or higher to the speakers capacity.

For example, if a 2.0 TV or soundbar claims Dolby AtmosĬompatibility, it means that it takes the 5/7.1.2/4 native signal and downmixesĪn approximation to the physical number of amps and speakers. The above cover the usual channels that a sound device canĭown-mix to. So, in a decent soundbar or hi-fi system, you will have separate speakers (and amps) for bass (sub-woofer), mid, and treble (tweeters). And this is because you need a larger speaker to push volumes of air for bass and a smaller, ‘shriller’ speaker for treble. Some headphones can get great bass because they have an excellent over-the-ear seal – less air to push. Physics precludes this in loudspeakers, although some headphones and earphones can come closer to this ideal.

But we have yet to find a single speaker that can do it all – reproduce the full range of frequency response. Speakers range from small 4-6mm earphone transducers to monster cones. There is an excellent article here that delves into sound signature nuances although it uses slightly different terms. We often refer to this as ‘synthetic sound’ – it is not bad, but it is not entirely natural. This can add a little bass, mid or treble, but it is not the speaker’s native signature. Most sound devices are naturally mid-centric and use some form of psycho-acoustic trickery via ‘tuning’ the DAC (Digital Analogue Converter) or an EQ to boost specific frequency by several dB. Many have equaliser and sound profile apps that can change the signatureĮntirely often resulting in ‘frankensound’.įlat means just that – and we seldom find it So, if we say something is warm and sweet, you can count on
Of course, you can have a combination of two or more, and Six sound signatures describe the natural state of the sound device. Though the music were really there, rather than merely reproduced. Sense of direction in the sound and provides a feeling of “air”, a reality as Generally hear this, but you know if it is missing. Dog whistle – top octave: 10-20kHz – you can’t.Upper Treble: 4-10kHz – this defines the character.Mid: 200-4kHz– this is where the action is, itĬovers the human voice and is the area where our ears are most sensitive … even.

Upper Bass: 100 to 200Hz – most small soundĭevices, like portable Bluetooth speakers, start here.
Midbass: 40-100Hz – if this is intact, you willīe getting just about all the musically important bass.More in your body that you hear in your ears Deep Bass: 16/20-40Hz – which you can often feel.Post-process, fill in the gaps and make the most of whatever we hear. Well, we have the world’s most powerful non-AI computer to You wonder how we can hear at all via two small ear canals. Oh, and throw in spatial variables like sound stage/separation (left/right, up/down,įorward/behind), echo (the reflection off walls), speed of sound and timbre and The eardrum) and feeling (subjective impressions that depend on musicalĪssociations, your mood at the moment, and a bunch of oh-so-human indefinables). Why hearing aids generally don’t boost volume, but boost lost frequency ranges.īut sound is a combination of hearing (tones and harmonics within Not uncommon for the elderly to only be able to hear to as low as 3kHz. As you get older, the top end usually progressively falls off – it is Humans generally hear frequencies from 20Hz (bass) to 20kHz It alsoĭepends on the ability of the encoder to get the important bits right and the reviewer’sĮars! Signature 101 and why we use it to rate sound devices Frequency response – the human hearing range
– the bit rate, sample rate, file format, and speaker construction. Why sound signature? Audio quality depends on so many things By comparison, a reviewer’s subjective comments from listening to their favourite soundtracks, although important, can vary wildly. The answer is that a sound signature is a consistent way to describe a devices ability to reproduce sound. A reader has asked about our use of sound signature in reviews for headphone, TV, soundbar, speakers, smartphones and other sound devices.
