Prueba de graves

Descubre dónde se acaban de verdad tus graves. Siete tonos fijos de 20 a 100 Hz más un barrido lento del extremo grave — el tono más bajo que oigas limpio es el suelo real de tu equipo.

⚠ Empieza con volumen bajo. Los tonos graves sostenidos a alto nivel pueden hacer tocar fondo al subwoofer y sobrecalentar altavoces pequeños.

Cómo leer tus resultados

El tono no suena: está por debajo del rango de tu equipo — normal en 20–40 Hz sin subwoofer. El tono suena más agudo que el siguiente: estás oyendo distorsión armónica, no la fundamental. Zumbido o traqueteo: algo está suelto — el altavoz, la rejilla o los muebles. Fuerte en un punto del barrido, muerto en otro: modos de sala — propiedad de la habitación, no del altavoz.

Preguntas frecuentes

¿Qué graves debería reproducir mi equipo?

Expectativas aproximadas: los altavoces de un portátil se rinden hacia 150–200 Hz; los altavoces Bluetooth pequeños hacia 80–100 Hz; unos altavoces de estantería decentes llegan a 50–60 Hz; unos buenos auriculares circumaurales reproducen 20–30 Hz (bajito pero audible); un subwoofer de verdad debe dar salida limpia a 25–30 Hz y muchos llegan a 20. Si un tono dos pasos por encima del rango declarado no suena, revisa volumen y colocación antes de culpar al hardware.

Oigo algo en el tono de 20 Hz con altavoces pequeños — ¿cómo?

Lo que oyes es casi seguro distorsión armónica, no 20 Hz. Cuando un altavoz pequeño se fuerza por debajo de su rango, produce armónicos a 40, 60 y 80 Hz que tu cerebro acepta como «una nota grave». Comprobación rápida: si el «tono» de 20 Hz suena parecido en altura al de 40 Hz, estás oyendo la distorsión, no la fundamental.

¿Por qué los graves suben y bajan al moverme por la habitación?

Modos de sala: las ondas de baja frecuencia miden metros y se reflejan entre paredes paralelas, creando puntos donde la onda se acumula (retumba) y puntos donde se cancela (muertos). Es una propiedad de la habitación, no un fallo del altavoz. Encuentra tus frecuencias problemáticas con la calculadora de modos de sala y prueba desde tu posición real de escucha.

¿A qué volumen reproduzco estos tonos?

Empieza alrededor de un cuarto de volumen y sube gradualmente. Las frecuencias graves se sienten más bajas de lo que miden — por las curvas isofónicas, 40 Hz necesita mucha más energía que 1 kHz para sonar igual de fuerte — así que es fácil llevar un altavoz pequeño a la distorsión o hacer tocar fondo al subwoofer sin darte cuenta. Rejillas que traquetean y paneles que zumban significan: baja el volumen.
