What is in the hair dryer recording?
The source is Hair dryer, sound 2680, by Pierre SIBANARCO, published by BigSoundBank under CC0. The local excerpt keeps the running motor and airflow while excluding starts, stops and speed changes.
It was converted to mono, peak-shaped, crossfaded and digitally level matched into a 9.5-second loop. Hair dryer and blow dryer refer to this same recording, not two different devices.
How does it differ from fan and vacuum noise?
This recording has its own bright air texture and motor detail. The fan sample is a generated hum; the vacuum uses a different appliance recording. Listen separately before choosing a background.
The sound name is not a claim that this recording is necessary, safer than quiet or proven to stop a baby crying. Stop if it attracts attention or is unwelcome.
Play the audio without using a hot appliance
The sound comes from your phone, computer or speaker. There is no need to run an actual hair dryer, which produces heat as well as noise.
Check the output before Play and keep equipment outside the sleep space. A browser percentage cannot show the level at a child’s ear.
