Less than 40dBA

What is dBA?

dB (the acronym for decibel) is a unit of sound measurement. It measures the loudness of a sound or the strength of a signal, computed as the signal to noise ratio. However, although dB is commonly used when referring to measuring sound, humans do not hear all frequencies equally. For this reason, sound levels in the low frequency end of the spectrum are reduced as the human ear is less sensitive at low audio frequencies than at high audio frequencies. In order to account for this, different weightings (A, B, C, D and Z) have been created to give a loudness measurement that takes into account how the human ear actually perceives sound. This weighting is known as dBA.

How We Test the dBA Level

To establish the dBA levels of ConceptD devices the laptop or desktop is placed on an ISO 7779 table inside a semi-anechoic room. Placed 25cm for laptops and 50cm for desktops, is an artificial head which replicates a real user and is capable of measuring the precise sound quality.

The noise level of <40dBA is obtained using SPECviewperf® 13 benchmark conditions.

Color Accuracy

What is Delta E?

Delta E is used to ensure the color being displayed closely matches what the human eye receives. It is also the difference between two colors designated as two points in the CIELAB color space. The higher the Delta E value, the lower the color accuracy. The color reproduction capabilities of the ConceptD series is further enhanced through complex algorithms, precise white balance, and gamma correction to match colors to their exact hue. Further professional precision is achieved by finely-tuning and calibrating displays for lifelike color reproduction.

ΔE < 1—indistinguishable difference
ΔE < 2—extremely small difference, only obvious to a trained eye
ΔE < 3—medium difference, obvious to an untrained eye
ΔE < 5—an obvious difference
ΔE > 6—a very obvious difference

Why Low Delta E Matters to Professionals

Creative professionals often need to have exact color replication. Displays with lower Delta E produce more accurate colors from in/out signals without color distortion, while also ensuring there is no color difference between multiple displays. For professionals who may work on one monitor and review on another, accurate and consistent color reproduction is key.
