B. Cat
C. Bird
D. All of these

Answer

### Step-by-Step Text Solution:

1. **Definition of Noise Pollution**:
- Noise pollution refers to the presence of unwanted or excessive sound in the environment that can cause harm to living beings.

2. **Understanding Noise**:
- Noise is defined as sound that is considered undesirable or irritating. It can disrupt normal activities and cause discomfort.

3. **Effects on Humans**:
- Excessive noise can lead to various health issues in humans. The human ear has eardrums that vibrate to allow us to hear sounds. If noise levels are too high, these vibrations can become harmful.
- Prolonged exposure to loud noise can damage the eardrum, potentially leading to hearing loss or other auditory problems.

4. **Impact on Animals**:
- Noise pollution is not only harmful to humans but also affects animals, such as birds and cats.
- Like humans, these animals use their ears to perceive sound, and excessive noise can disturb their natural behavior and communication.

5. **Hearing Range Differences**:
- Humans can typically hear sounds in the range of 20 Hz to 20 kHz. However, many birds and cats have a broader hearing range, which means they can hear sounds that are higher or lower than what humans can perceive.
- This extended range makes them more susceptible to disturbances caused by noise pollution.

6. **Conclusion**:
- Overall, noise pollution is harmful to humans, birds, and cats due to its potential to cause physical damage to hearing and disrupt normal life activities.
