Managing sound levels at an information handling system

An information handling system, comprising:

• a fan;
• a microphone configured to record sound levels of an environment of the information handling system;
• a processor;
• memory media storing instructions executable by the processor to perform operations, comprising:
• determining, for each time duration of multiple time durations over a first time period, multiple instantaneous sound levels of the time duration of an environment of the information handling system;
• calculating, for each time duration of the multiple time durations over the first time period, an average sound level of the time duration based on the multiple instantaneous sound levels of the time duration;
• determining, based on the average sound level of each time duration of the multiple time durations over the first time period, a lowest average first sound level for the first time period;
• setting the lowest average first sound level as an ambient sound level of the environment of the information handling system for the first time period;
• adjusting, for the first time period, a fan speed of a fan of the information handling system based on the ambient sound level of environment such that a noise level of the fan is less than the ambient sound level of the environment for the first time period;
• determining, for each time duration of multiple time durations over a second time period, multiple instantaneous sound levels of the time duration of the environment of the information handling system;
• calculating, for each time duration of the multiple time durations over the second time period, an average sound level of the time duration based on the multiple instantaneous sound levels of the time duration;
• determining, based on the average sound level of each time duration of the multiple time durations over the second time period, a lowest average second sound level for the second time period;
• setting the lowest average second sound level as the ambient sound level of the environment of the information handling system for the second time period;
• and
• adjusting, for the second time period, the fan speed of the fan of the information handling system based on the ambient sound level of environment such that the noise level of the fan is less than the ambient sound level of the environment for the second time period,
• wherein the second time period partially overlaps with the first time period.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• determining, for each time duration of multiple time durations over a first time period, multiple instantaneous sound levels of the time duration of an environment of the information handling system;
• calculating, for each time duration of the multiple time durations over the first time period, an average sound level of the time duration based on the multiple instantaneous sound levels of the time duration;
• determining, based on the average sound level of each time duration of the multiple time durations over the first time period, a lowest average first sound level for the first time period;
• setting the lowest average first sound level as an ambient sound level of the environment of the information handling system for the first time period;
• adjusting, for the first time period, a fan speed of a fan of the information handling system based on the ambient sound level of environment;
• determining, for each time duration of multiple time durations over a second time period, multiple instantaneous sound levels of the time duration of the environment of the information handling system;
• calculating, for each time duration of the multiple time durations over the second time period, an average sound level of the time duration based on the multiple instantaneous sound levels of the time duration;
• determining, based on the average sound level of each time duration of the multiple time durations over the second time period, a lowest average second sound level for the second time period;
• setting the lowest average second sound level as the ambient sound level of the environment of the information handling system for the second time period;
• and
• adjusting, for the second time period, the fan speed of the fan of the information handling system based on the ambient sound level of environment such that the noise level of the fan is less than the ambient sound level of the environment for the second time period,
• wherein the second time period partially overlaps with the first time period.
