Sound limit in industry is

Options

A. 75 dB
B. 55dB
C. 45dB
D. 30 dB

Answer

To determine the sound limit in industry, we can follow these steps:

### Step 1: Understand the Context
We need to find the permissible noise exposure limits in industrial settings as defined by regulatory bodies.

### Step 2: Identify the Relevant Organization
The Occupational Safety and Health Administration (OSHA) is the organization that sets these standards for noise exposure in the workplace.

### Step 3: Know the Decibel Levels
According to OSHA, the permissible noise exposure limits are established to prevent hearing loss.

### Step 4: Determine the Key Decibel Level
- For industrial areas, OSHA specifies that the permissible noise level is 75 decibels (dB).
- Additionally, if noise levels exceed 85 dB, a hearing conservation program is required.

### Step 5: Compare with Other Options
- The other options provided (55 dB, 45 dB, and 30 dB) are lower than the industrial limit.
- The correct option for the industrial sound limit is therefore 75 dB.

### Final Answer
The sound limit in industry is **75 decibels**.
