Waveform Audio File Format (WAVE, or WAV due to its filename extension; [3] [6] [7] pronounced / w æ v / or / w eɪ v / [8]) is an audio file format standard for storing an audio bitstream on personal computers. The format was developed and published for the first time in 1991 by IBM and Microsoft.
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.

The day–evening–night noise level or L den is a 2002 European standard to express noise level over an entire day. It imposes a penalty on sound levels during evening and night [ 1 ] and it is primarily used for noise assessments of airports , busy main roads, main railway lines and in cities over 100,000 residents.
3-D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space.
It changes the disturbing echo of the sound into a mild reverb which decays over time. Diffraction is the change of a sound wave's propagation to avoid obstacles. According to Huygens’ principle, when a sound wave is partially blocked by an obstacle, the remaining part that gets through acts as a source of secondary waves. [17]
In addition, sounds can also be long and soft as well as short and loud. [7] Onset time of the noise during the night: The ISCD-2 established latency of noises after falling asleep ranging from 2 to 6 h. [11] However, in some published cases the onset time of the noises is reported as being shorter (3 min [16]). Association with respiratory ...
