Here, ‘p’ is the root mean square value of the sound pressure in Pa (or N/m 2 ). This logarithmic ratio is the dimensionless unit of Power, the decibel (dB). The focus on balancing a mix of high and low frequencies results in an even, reliable and constant sound output. Sound Pressure Level or SPL is the sound or noise measurement expressed as a logarithmic ratio of sound pressure to a reference sound pressure. Pink noise fans differ in that they succeed in achieving balance. The results often vary and can range from static, hissing, rattling and everything in between. The aim is to drown out any noise that may disturb your rest while establishing a noise pattern for concentration. There were some conflicting readings and, in many cases, authors did not specify at what distance the readings were taken or what the musician was actually playing. White noise fans are less balanced in that they gather a collection of opposing frequencies to create a repetitive string of sounds. Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin, M.Sc., Aud (C), FAAA, Centre for Human Performance & Health, Ontario, Canada. What is the difference between white noise and pink noise?īoth white and pink noise fans can be extremely useful in calming the body into a generous night's sleep. The lightweight, budget-friendly Honeywell HT-900 is (ahem) a fan favorite close to 87,000 Amazon reviewers gave it a five-star rating. The Honeywell Double Bladed Pedestal Fan comes with the added bonus of delivering 15% more air volume. Ranging from personal to whole room cooling, these oscillating fans come with multiple cooling speeds for increased comfort. Honeywell Comfort Control Fans will spread a steady amount of cool air in a wide area due to their oscillation. Let the soothing sound of these powerful fans lull you to sleep while also keeping your surroundings cool and comfortable. QuietSet Fans are fitted with aerodynamic blades and a cone shaped air diffuser that’s engineered to deliver a powerful cooling experience with reduced noise. Honeywell QuietSet Fans feature a range of quiet operation levels including “sleep” and “white noise”. You see, the difference between 50 decibels and 75 decibels is actually comparable to the noise level difference between a refrigerator’s soft humming (50 decibels) and a vacuum cleaner (75 decibels). And while that may not seem like a huge variance, it is. This is accomplished by physically separating the motor housing the air register at the ceiling level. Heat pump decibel ratings can range anywhere from the low 50s to 90s. The advanced whole-house fans are very quiet, as you can see.
Available in personal to whole room cooling options, Honeywell TurboForce Fans feature increased flexibility with their ability to pivot in multiple directions. The sound level of an advanced whole house fan is very similar to that of a standard A/C unit running in your home. Honeywell TurboForce Fans are primarily centered on accessibility and performance while delivering an altogether quiet experience (25% quieter than comparable fans).
