Hearing changes can be perplexing and concerning, especially for someone with absolute pitch, as you have described. The sensation of hearing sounds at a lower pitch or frequency than usual can stem from various causes, and understanding these can help in determining the appropriate course of action.

Firstly, it’s essential to consider the possibility of a temporary condition, such as a viral infection or congestion due to a recent cold. When you experience a cold, the Eustachian tube, which connects the middle ear to the back of the throat, can become inflamed or blocked. This blockage can lead to a sensation of fullness in the ear and may alter how sound is perceived. If there is fluid buildup in the middle ear, it can dampen higher frequencies more than lower ones, leading to the perception of sounds being lower in pitch. This condition is often referred to as conductive hearing loss, where sound transmission is impeded.

Another potential cause could be sensorineural hearing loss, which affects the inner ear or auditory nerve. This type of hearing loss can result from exposure to loud noises, which is particularly relevant given your background as a drummer and frequent headphone use. Prolonged exposure to loud sounds can damage the hair cells in the cochlea, leading to distorted sound perception, including the phenomenon of hearing sounds as lower in pitch.
Additionally, certain medications, particularly ototoxic drugs, can affect hearing. If you were prescribed medication during your recent illness, it’s worth discussing with your healthcare provider whether any of these could be contributing to your symptoms.

Moreover, the perception of sound can also be influenced by psychological factors. Stress or anxiety, particularly if you are concerned about your hearing, can lead to heightened awareness of auditory changes. This can create a feedback loop where the anxiety about hearing changes exacerbates the perception of those changes.

Given these possibilities, it is crucial to seek a thorough evaluation from an ear, nose, and throat (ENT) specialist. They can perform a comprehensive hearing test, including audiometry, to assess your hearing across different frequencies and determine if there is any significant loss or distortion. Additionally, they may conduct tympanometry to evaluate the middle ear's function and check for any fluid buildup or Eustachian tube dysfunction.

If your hearing changes persist, further investigations such as imaging studies (like an MRI) might be warranted to rule out any structural issues in the auditory pathways.
In the meantime, it would be advisable to avoid exposure to loud noises and to monitor your symptoms closely. If you notice any worsening of your condition, such as increased ear pain, tinnitus (ringing in the ears), or balance issues, seek medical attention promptly.

In summary, while the changes in your hearing can be concerning, they may be temporary and related to your recent illness or noise exposure. A thorough evaluation by a healthcare professional will provide clarity and guide you toward the appropriate treatment or management strategies.
