The speed of sound in a medium depends on the properties of that medium, such as its density and elasticity. In general, the speed of sound is relatively constant within a given medium under normal conditions. In dry air at sea level and at a temperature of around 20 degrees Celsius, the speed of sound is approximately 343 meters per second (or about 767 miles per hour).
Therefore, the perception of one sound being faster or slower than another is usually related to the frequency or pitch of the sound rather than the actual speed at which the sound waves propagate through the medium.
Higher-frequency sounds, such as the buzzing of bees or the screeching of birds, have shorter wavelengths and are perceived as higher-pitched. Lower-frequency sounds have longer wavelengths and are perceived as lower-pitched.
If you are referring to the time it takes for a sound to reach your ears from its source, that depends on the distance between you and the sound source, as well as the speed of sound in the medium through which the sound is traveling. If the source of the buzzing sound (bees) or screeching sound (bird) is at the same distance from you, you would hear both sounds at approximately the same time.
However, keep in mind that different sounds can have different propagation characteristics. For example, if there are obstacles or variations in the medium that cause the sound waves to reflect, refract, or diffract, it can affect the path and arrival time of the sound waves at your location. This can lead to variations in the perceived timing of different sounds, especially if they are coming from different directions or encountering different environmental conditions.
