A SIGNAL is any sound or message that is intended to be listened to, measured, or recorded in contrast to NOISE, which is unwanted sound.
Since sound signals complement their AMBIENT or KEYNOTE context in a similar way that figure and ground are related in visual perception, sound signals are always examined in reference to that context in SOUNDSCAPE investigations. As a result, studying signals also reveals vital details about the whole audio environment. For example, the level of emergency warning signals has increased in lockstep with the AMBIENT NOISE LEVEL of cities over the past century.
Any of the following methods can be used to research sound signals:
- based on their acoustic properties, which may indicate a recognised code or other pattern pertaining to their use (see TYPOLOGY);
- subjectively, by their personally perceived meanings;
- historically, in accordance with their development within a particular social context (see MORPHOLOGY);
- comparably, by type and function in different cultures or periods;
- symbolically, in accordance with their connotative and associative meanings.
Sound signals are significant because they control community life and reveal its character. Those with historical value can be referred to as SOUNDMARKS. A sound signal's profile, also known as the acoustic space, can be thought of as its sphere of influence. With increasing background noise levels in contemporary urban areas, many community signals are becoming physically and acoustically less noticeable.
