elevation
Definition
The elevation property is used to give the impression that a sound is coming from a specific direction. This property more naturally reflects the way in which we hear sound. The listening experience is enhanced when elevation is used in conjunction with azimuth. Whereas elevation identifies the vertical direction that sound comes from (as shown in the illustration below), azimuth provides a sense of horizontal direction. The two together create a more 3-dimensional listening experience.
To get the effects of the azimuth and elevation properties, special audio equipment may be required, such as binaural headphones or multi-speaker setups.
Example
h1 {elevation: above}q, blockquote {elevation: 60deg}p {elevation: level}
Characteristics
Possible values
- angle
- Specifies the elevation as an angle, between
-90deg and 90deg. 0deg marks the forward horizon, which loosely speaking is level with the listener's ears. 90deg is directly overhead, and -90deg is directly below. below- This value is equivalent to
-90deg. level- This value is equivalent to
0deg. above- This value is equivalent to
90deg. higher- Adds 10 degrees to the current elevation.
lower- Subtracts 10 degrees from the current elevation.
inherit- Use the same computed value as the parent element for this property.
