The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary.
The changing of atmospheric pressure does not change the sound of Musical Instruments in a concert hall or in a room; see link: "Speed of Sound in Air and the effective Temperature".

It is the a little bit the humidity, but more the temperature.

A Different Perspective:
Pressure does affect sound.
The speed of sound travelling varies at different pressures.

We measure the sound pressure in pascals or the sound pressure level SPL in decibels. That is a sound field quantity.

Why are sound waves are described as pressure waves?
Sound waves are described as pressure waves because waves produces pressure by which sound is produces
How does sound waves affect whales?
The sound waves affect their sence of directions.
What type of sound wave are they that they allow sound to travel?
Sound waves are pressure waves.
What are sound waves made up?
pressure waves
What waves reach our ears?
Sound (pressure) waves.
How does air pressure change the effect of sound waves compression and rarefaction?
Air pressure does not affect transverse sound waves. The temperature is most important to do that. The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavlength of the sound. Look at the link: "Speed of Sound in Air and the effective Temperature".
Waves that disturb matter?
Sound waves, pressure waves, longitudinal waves.
What are a sound wave?
Yes, sound waves are pressure waves that travel through matter.
What does amplitude of a sound wave determine?
Amplitude is the volume of the sound in sound waves. The higher the Amplitude, the louder is the sound. Sound waves are pressure or compression waves in the material through which the sound is traveling. The pressure or compression waves also result in small longitudinal displacements of the atoms or molecules. The amplitude of the sound wave determines the range of variation of pressure, compression, or displacement.
What are some examples of longitude waves?
sound waves aka pressure waves
What waves reach our ears on playing guitar?
Sound waves (which are pressure waves).
Sound can best be thought of as?
Pressure waves.
