What does STPR mean in ELECTRONICS
STPR stands for SideTone Power Rating. It is a measure of the power of the sidetone signal in a telephone headset. Sidetone is the sound of the user's own voice that is fed back into the earpiece. It is important for maintaining a natural speaking voice and for avoiding feedback.
STPR meaning in Electronics in Academic & Science
STPR mostly used in an acronym Electronics in Category Academic & Science that means SideTone Power Rating
Shorthand: STPR,
Full Form: SideTone Power Rating

STPR Levels
STPR levels are typically measured in decibels (dB). The optimal STPR level varies depending on the individual user and the specific application. However, most experts recommend an STPR level of -10 dB to -15 dB. This level provides sufficient sidetone to maintain a natural speaking voice without causing feedback.
Benefits of Sidetone
Sidetone has several benefits, including:
- Natural speech: Sidetone helps the user to maintain a natural speaking voice by providing feedback on their own volume and intonation.
- Reduced feedback: Sidetone can help to reduce feedback by canceling out the sound of the user's voice before it reaches the microphone.
- Improved speech intelligibility: Sidetone can improve speech intelligibility by making it easier for the user to hear their own voice.
Essential Questions and Answers on SideTone Power Rating in "SCIENCE»ELECTRONICS"
What is SideTone Power Rating (STPR)?
STPR refers to the power level of the sound that is transmitted back to the user's ear during a phone call. It determines the loudness of the user's own voice as they speak into the microphone.
Why is STPR important?
STPR ensures that the user can hear themselves clearly during a call, which helps to prevent shouting or speaking too softly. It also helps to reduce background noise and improve overall call quality.
What is the typical range of STPR values?
STPR values typically range from -20 to +20 dB, with 0 dB representing a neutral setting. A higher STPR value indicates a louder sidetone.
How is STPR measured?
STPR is measured using a special acoustic probe that is inserted into the earpiece of the phone. The probe measures the sound pressure level (SPL) of the sidetone and converts it into a dB value.
How can I adjust the STPR on my phone?
STPR adjustments are typically not possible for most consumer-grade phones. However, some professional headsets and specialized communication devices may offer adjustable STPR settings.
Final Words: STPR is an important factor to consider when choosing a telephone headset. The optimal STPR level will vary depending on the individual user and the specific application. However, most experts recommend an STPR level of -10 dB to -15 dB for optimal performance.
